FIELD OF THE INVENTION
The invention relates to quaternized fatty amines, amidoamines, and derivative compositions that originate from natural resources, particularly natural oils and their metathesis products.
BACKGROUND OF THE INVENTION "Fatty amines" generally have a non-polar chain of six or more carbons, typically 6-30 carbons, and at least one polar end group comprising or derived from an amine, for example, a tertiary amine. Fatty amines have value in and of themselves, but they are commonly quaternized using a variety of alkylating agents to provide quats of grease amine, betaine, sulfobetaines or other quaternized derivatives having an expanded utility.
Quaternized fatty amines have been used in a wide variety of end-use applications, including fabric softener (see Pat. Nos. US5,574,179 and US 6,004,913), shampoos and hair conditioner (Pat. Nos. US4,744,977, US6,322,778 and US7,951,762), rough surface cleaners (Pat. No. US6,268,324 and US6,821,943), cosmetics (Pat. Nos. US6,919,074 and US7,074,395), oral care (Pat. No. US7 .534.816), soaps or antimicrobial cleaners (Pat. No. US6.010.991 and Publ. Ped. Pat. No. US2004 / 0071653), oilfield applications (Pat. Nos. US7.422.064 and 7.776.798) and agricultural uses (Publ. Ped. Pat. Nos. US 2011/0015071 and US2010 / 0016163).
Quaternized fatty amines can be made by converting fatty acids or esters with a secondary amine to the derived amide, followed by reduction of the carbonyl to provide a terminal tertiary amine which is reacted with a quaternizing agent. In a preferential approach, the
Petition 870180168303, of 12/27/2018, p. 13/22
2/79 reduction step is avoided by reacting a fatty ester with a tertiary amine substituted with aminoalkyl. For example, N, N-dimethyl-1,3propanediamine (DMAPA) reacts with a fatty methyl ester to provide a grease amidoamine. Amidoamine has a terminal tertiary amine group that is easily quaternized. Common quaternizing agents are dimethyl sulfate, methyl chloride, benzyl chloride, ethylene oxide and others.
The fatty acids or esters used to make fatty amines and their derivatives are generally made by hydrolysis or transesterification of triglycerides, which are typically animal or vegetable fats. Consequently, the greasy portion of the acid or ester will typically have 6-22 carbons with a mixture of saturated and internally unsaturated chains. Depending on the source, the fatty acid or ester often has a preponderance of component Ci ₆ to C22 · For example, soybean oil methanolysis provides the saturated methyl esters of paimitic (Ci ₆ ) and stearic acid (C ₁₈ ) and 15 unsaturated methyl esters of oleic acid (C ₈ monounsaturated), linoleic (di-unsaturated C ₈₎ and α-linolenic (tri-unsaturated C ₈₎ acid have unsaturation in these configuration or solely or predominantly cis.
Recent improvements in metathesis catalysts (see JC Mol, Green __________Chem. 4 (2002) 5) provide an opportunity to generate reduced chain length, monounsaturated raw materials, which are valuable for making detergents and surfactants from oils natural rich in Ci ₆ to C22, such as soybean oil or palm oil. Soy oil and palm oil can be more economical than, for example, coconut oil, which is a traditional starting material for making detergents. As Professor Mol explains, metathesis refers to the conversion of olefins into new products through the rupture and reforming of carbon-carbon double bonds mediated by transition metal-carbene complexes. Auto-metathesis of an unsaturated fatty ester can provide a balance mixture of starting material, an internally unsaturated hydrocarbon and an unsaturated diester. For example, methyl oleate (c / s930 methyl octadecenoate) is partially converted to 9-octadecane and 9octadecan-1,18-dimethyl dioate, with both products predominantly consisting of trans isomer. Metathesis effectively isomerizes the cis double bond of methyl oleate to provide a balance mixture of cis and trans isomers in both starting materials and 35 "unconverted" metathesis products, with trans isomers predominating.
3173
Cross-metathesis of unsaturated fatty esters with olefs generates new olefins and new unsaturated esters that may have reduced chain length and this can be difficult to do otherwise. For example, cross-metathesis of methyl oleate and 3-hexene provides 3-dodecene and 9-dodecenoate of 5 methyl (see also U.S. Pat. No. 4,545,941). Terminal olefins are particularly desirable synthetic targets, and Elevance Renewable Sciences, Inc. recently described an improved way to prepare them by cross-methosing an internal olefin and an α-olefin in the presence of an ruthenium alkylidene catalyst (see Publ. Ped. Pat. No. US2010 / 0145086). A variety of cross-metathesis reactions involving an α-olefin and an unsaturated fatty ester (as the source of internal olefin) are described. Thus, for example, the reaction of soy oil with propylene followed by hydrolysis provides, among other things, 1decene, 2-undecenes, 9-decenoic acid, and 9-undecenoic acid. Despite the availability (cross-metathesis of natural oils and olefins) of unsaturated fatty esters having reduced chain length and / or predominantly trans configuration of unsaturation, fatty amines and their derivatives made from these raw materials seem to be unknown. In addition, quaternized fatty amines and their derivatives were not made from Ci ₈ ________ unsaturated diesters that can be easily made by auto-metathesis of a natural oil.
In short, traditional sources of esters and fatty acids used to make quaternized fatty amines and their derivatives generally have predominantly (or exclusively) cis isomers and are devoid of unsaturated fatty portions of relatively short chain (for example, Cio or 25 C12). Metathesis chemistry provides an opportunity to generate precursors having shorter chains and mainly trans isomers, which could transmit improved performance when the precursors are converted into downstream compositions (for example, surfactants). New dysfunctional Cw quaternized fatty amines and derivatives are also potentially available from C ₁₀ oil or unsaturated acid or ester auto-metathesis. In addition to expanding a variety of precursors, the unsaturation present in the precursors allows additional functionalization, for example, through sulfonation or sulfitation.

DETAILED DESCRIPTION OF THE INVENTION ________________________________ In one aspect, the _____ invention relates to the composition of quaternary ammonia, betaine or sulfobetaine derived from a grease amine. The grease amine is made from a metathesis-derived C10-C17 monosaturated acid, octadecene-1,18-dioic acid or its ester derivatives.
C10-C17 monounsaturated acid, octadecane-1,18-dioic acid, or its ester derivatives, used as a reagent, is derived from the metathesis of a natural oil. Traditionally, these materials, particularly short-chain acids and derivatives (for example, 9-decylenic acid or 9-dodecylenic acid) have been difficult to obtain, except in laboratory-scale quantities at considerable expense. However, because of recent improvements in metathesis catalysts, these acids and their ester derivatives are now available in volume at a reasonable cost. Thus, C10-C17 monounsaturated acids and esters are conventionally generated through cross-metathesis of natural oils with olefins, preferably α-olefins, and particularly ethylene, propylene, 1-butene, 1-hexene, 1-octene, and the like. Auto-metathesis of natural oil or a precursor of C10 acid or ester (for example, methyl 9-decenoate) provides the diester or diacid in ideal yield when it is the desired product.
5/79. Preferably, at least a portion of the C10C17 monounsaturated acid has "Δ ⁹ " unsaturation, that is, the carbon-carbon double bond in the C ₁₀ -Ci ₇ acid is in the 9- position with respect to the acid carbonyl. In other words, there are preferably seven carbons between the acid carbonyl group and the 5 olefin group in C9 and C10. For Cu to C17 acids, an alkyl chain of 1 to 7 carbons, respectively, is attached to C10. Preferably, the unsaturation is at least 1 mol% of trans-Δ ⁹ , more preferably at least 25 mol% of trans-Δ ⁹ , more preferably at least 50 mol% of trans-Δ ⁹ , and even more preferably at minus 80% of trans-Δ ⁹ . Unsaturation can be greater than 90 mol%, greater than 95 mol%, or even 100% transΔ ⁹ . In contrast, naturally occurring fatty acids that have Δ ⁹ unsaturation, for example, oleic acid, usually have -100% cis isomers.
Although a high proportion of trans geometry (particularly trans-Δ ⁹ geometry) may be desirable in the quaternized compositions 15 derived from metathesis of the invention, the person skilled in the art will recognize that the exact configuration and location of the carbon-carbon double bond will depend on the reaction conditions, catalyst selection, and other factors. Metathesis reactions are commonly accompanied by isomerization, which _____________________________________________________ may or may not be desirable. See, for example, G. Djigoué and M. Meier, Appl. Catai.
A: General 346 (2009) 158, especially Fig. 3. Therefore, the person skilled in the art can modify the reaction conditions to control the degree of isomerization or change the proportion of cis and trans isomers generated. For example, heating a metathesis product in the presence of an inactivated metathesis catalyst can allow the person skilled in the art to induce double bond migration to provide a lower proportion of product having trans-Δ ⁹ geometry.
A high proportion of trans isomer content (in relation to the usual all cis configuration of the ester or natural monounsaturated acid) gives different physical properties to compositions of quaternary ammonium, betapine 30 or sulfobetaine made from them, including, for example, modified physical form , melting range, compactability, and other important properties. These differences should allow formulators using the quaternary compositions to have greater latitude or broader choices as they use them in cleaners, fabric treatment, personal care, agricultural uses, and other end uses.
6/79
Suitable C10-C17 monounsaturated acids derived from metathesis include, for example, 9-decylenic acid (9-decenoic acid), 9undecenoic acid, 9-dodecylenic acid (9-dodecenoic acid), 9-tridecenoic acid, 9-tetradecenoic acid, 9-pentadecenoic acid, 9-hexadecenoic acid, 9heptadecenoic acid, and the like, and their ester derivatives.
Generally, cross-metathesis or auto-metathesis of natural oil is followed by separation of an olefin stream from a modified oil stream, typically by removing the most volatile olefins by distillation. The stream of modified oil is then reacted with a lower alcohol, typically methanol, to provide glycerin and a mixture of alkyl esters. This mixture normally includes saturated C6-C22 alkyl esters, predominantly Cw-Cie alkyl esters, which are essentially spectators in the metathesis reaction. The rest of the product mixture depends on whether auto-metathesis or cross-metathesis is used. When the natural oil is self-metatized and then transesterified, the alkyl ester mixture will include an unsaturated diester C-te · When the natural oil is cross-metatized with an α-olefin and the product mixture is transesterified, the mixture of The resulting alkyl ester includes a C ₁₀ unsaturated alkyl ester and one or more Cn to C ₁₇ unsaturated alkyl ester co-products in addition to the glycerin by-product. The terminally unsaturated product C10 is accompanied by different co-products, depending on which olefin (s) is used as a cross metathesis reagent. Therefore, 1-butene provides a C12 unsaturated alkyl ester, 1-hexene provides a C14 unsaturated alkyl ester, and so on. As shown in the examples below, the C10 unsaturated alkyl ester is readily separated from the Cn to C-17 unsaturated alkyl ester and each is easily purified by fractional distillation. These alkyl esters are excellent starting materials for making the quaternized grease amine or amidoamine compositions of the invention.
Natural oils suitable for use as a raw material to generate C10-C17 monounsaturated acid, octadecane-1,18-dioic acid, or its ester derivatives from auto-metathesis or cross-metathesis with olefins, are well known. Suitable natural oils include vegetable oils, algae oil, animal fats, pine oils, oil derivatives, and combinations thereof. Therefore, suitable natural oils include, for example, soybean oil, palm oil, rapeseed oil, coconut oil, palm kernel oil, sunflower oil, safflower oil, sesame oil, corn oil, olive oil, peanut oil, cottonseed oil, canola oil, castor oil, tallow, lard, fat
7/79 chicken, fish oil, and the like. Soy oil, palm oil, rapeseed oil, and their mixtures are preferred natural oils.
Genetically modified oils, for example, soybean oil rich in oleate or genetically modified algae oil, can also be used.
Preferred natural oils have substantial unsaturation, as this provides a reaction site for the metathesis process to generate olefins. Particularly preferred are natural oils that have a high content of unsaturated fatty groups derived from oleic acid. Therefore, particularly preferred natural oils include soy oil, palm oil, seaweed oil, 10 and rapeseed oil.
A modified natural oil, such as a partially hydrogenated vegetable oil, can be used instead of or in combination with natural oil. When a natural oil is partially hydrogenated, the unsaturation site can migrate to a variety of positions in the main structure of hydrocarbon 15 of the fatty ester half. Because of this trend, when the modified natural oil is self-metatized or cross-metatized with the olefin, the reaction products will have a different and generally more extensive distribution compared to the product mixture generated from a non-natural oil. modified. However, products generated from the modified natural oil 20 are converted similarly to the quaternized grease amine or amidoamine compositions of the invention.
An alternative to using a natural oil as a raw material to generate C10-C17 monounsaturated acid, octadecane-1,18-dioic acid, or its ester derivatives from auto-metathesis or cross-metathesis with olefins, is a 25 monounsaturated fatty acid obtained by hydrolysis of a vegetable oil or animal fat, or an ester or salt of such an acid obtained by esterification of a fatty acid or carboxylate salt, or by transesterification of a natural oil with an alcohol. Also useful as starting compositions are esters, acids, and polyunsaturated fatty carboxylate salts. The salts can include an alkali metal 30 (for example, Li, Na, or K); an alkaline earth metal (for example, Mg or Ca);
a Group 13-15 metal (for example, B, Al, Sn, Pb, or Sb), or a transition metal, lanthanide or actinide. Additional suitable starting compositions are described on p. 7-17 of PCT application WO 2008/048522, the contents of which are hereby incorporated by reference.
The other reagent in the cross metathesis reaction is an olefin. Suitable olefins are internal or α-olefins having one or more double bonds
8/79 carbon-carbon. Mixtures of olefins can be used. Preferably the olefin is an α-olefin monounsaturated C ₂ -C _0, more preferably one monounsaturated C2 -C8 alpha olefin. Preferred olefins also include C4-C9 internal olefins. Thus, olefins suitable for use include, for example, 5 ethylene, propylene, 1-butene, cis and trans-2-butene, 1-pentene, isohexylene, 1hexene, 3-hexene, 1-heptene, 1-octene, 1 -nonene, 1-decene, and the like, and mixtures thereof.
Cross-metathesis is performed through the reaction of natural oil and olefin in the presence of a homogeneous or heterogeneous metathesis catalyst. 10 Olefin is omitted when natural oil is self-metatized, but the same types of catalysts are generally used. Suitable homogeneous metathesis catalysts include combinations of a transition metal halide or oxohalide (eg, WOCI4 or WCI ₆ ) with an alkylation co-catalyst (eg, Me4Sn). Preferred homogeneous catalysts are well-defined alkylidene (or carbene) complexes of transition metals, particularly Ru, Mo, or W. These include first and second generation Grubbs catalysts, Grubbs-Hoveyda catalysts, and the like. Suitable alkylidene catalysts have the general structure:
_________________________________________________________________ M [X ¹ X ² L ¹ L ² (L ³ ) n] = C _m = C (R ¹ ) R ² where M is a transition metal of Group 8, L ¹ , L ² , and L ³ are binders neutral electron donors, n is 0 (such that L ³ may not be present) or 1, m is 0, 1, or 2, X ¹ and X ² are anionic ligands, and R ¹ and R ² are independently selected from of H, hydrocarbyl, substituted hydrocarbyl, hydrocarbyl containing heteroatom, substituted hydrocarbyl containing heteroatom, and functional groups.
Any two or more of X ¹ , X ² , L ¹ , L ² , L ³ , R ¹ and R ² can form a cyclic group and any one of these groups can be attached to a support.
First generation Grubbs catalysts fall into this category where m = n = 0 and particular selections are made for η, X ¹ , X ² , L ¹ , L ² , L ³ , R ¹ and R ² as described in Publ. Ped. Pat. No. US2010 / 0145086 (“publication 30 '086”), the teachings of which refer to all metathesis catalysts are incorporated here by reference
Second generation Grubbs catalysts also have the general formula described above, but L ¹ is a carbene binder where the carbon carbon is flanked by N, O, S, or P atoms, preferably by two N. 35 atoms. The carbene linker is part of a cyclic group. Examples of <
I
9/79 suitable second generation Grubbs catalysts also appear in publication ‘086.
In another class of suitable alkylidene catalysts, L ¹ is a strongly coordinating electron neutral donor as in the first and second generation Grubbs catalysts, and L ² and L ³ are weakly coordinating electron neutral donor ligands in the form of optionally substituted heterocyclic groups. . Therefore, L ² and L ³ are pyridine, pyrimidine, pyrrole, quinoline, thiophene, or the like.
In yet another class of suitable alkylidene catalysts, a pair of substituents is used to form a bi or tridentate linker, such as a bisphosphine, dialkoxide, or alkyl diketonate. Grubbs-Hoveyda catalysts are a subset of this type of catalyst in which L ² and R ² are linked. Typically, a nitrogen or neutral oxygen coordinates with the metal while also being attached to a carbon that is α-, β-, or γ- with reference to the carbene carbon to provide the bidentate ligand. Examples of suitable Grubbs-Hoveida catalysts appear in Ό86.
The structures below provide only a few illustrations of suitable catalysts that can be used:
PCy ₃
Heterogeneous catalysts suitable for use in the reaction of self-synthesis or cross-metathesis include certain compounds of rhenium and molybdenum as described, for example, by JC Mol in Green Chem. 4 (2002) 5 on pp. 11-12. Particular examples are catalytic systems that include Re2O ₇ in alumina promoted by an alkylation co-catalyst, such as a lead-tin, germanium, or silicon tetraalkyl compound. Others include M0CI3 or M0CI5 on tetraalkyl-tin activated silica.

For additional examples of catalysts suitable for self-metathesis or cross-metathesis, see Pat. No. US4,545,941, the teachings of which are incorporated herein by reference, and references cited therein.
Fatty amines used to make the quaternized compositions of the invention can be made by reacting a metathesis-derived C10-C17 monounsaturated acid, octadecene-1,18-dioic acid or its ester derivatives with a secondary amine, followed by reduction of the resulting grease amide . They can also be done by reducing an acid derived from metathesis or an ester derivative to a fatty alcohol, followed by amination of the fatty alcohol.
Thus, intermediates for the fatty amines of the invention are fatty alcohol or fatty amides derived from metathesis.
In one aspect, the ester derivative is a lower alkyl ester, especially a methyl ester. The lower alkyl esters are preferably generated by transesterification of a metathesis-derived triglyceride. For example, cross-metathesis of a natural oil with an olefin, followed by removal of unsaturated hydrocarbon metathesis products by stripping, and then transesterification of the modified oil component with a lower alkanol under basic conditions provides a mixture of unsaturated lower alkyl esters . The unsaturated lower alkyl ester mixture can be used "as is" to make 20 precursors to the fatty amines or can be purified to isolate particular alkyl esters before making fatty amides.
In another aspect, the ester derivative is the metathesis-derived triglyceride discussed in the previous paragraph. Instead of transesterification of the metathesis-derived triglyceride with a lower alkanol to generate lower alkyl esters as described above, the metathesis-derived triglyceride, following olefin stripping, is reacted directly with secondary amine to make a mixture of grease amide, which is then reduced to provide a grease amine. Alternatively, the metathesis-derived triglyceride, after olefin stripping, is reduced to provide a fatty alcohol mixture, which is then aminated to provide the grease amine mixture.
The person skilled in the art will appreciate that the "ester derivative" here encompasses other equivalents of acyl, such as acid chlorides, acid anhydrides or the like, in addition to the lower alkyl esters and glyceryl esters discussed above.
In a synthetic approach, the metathesis-derived or 35-derivative acid is reacted with a secondary amine to provide a grease amide, followed by reduction of the grease amide to provide the grease amine.
11/79
Suitable secondary amines have a hydrogen and two hydrocarbyl groups attached to nitrogen. The hydrocarbyl groups are preferably C1-C20 alkyl, C ₆ -C ₂ o aryl. or C7-C20 linear, branched or cyclic arylalkyl. More preferably, both of the hydrocarbon groups are C 1 -C ₆ alkyl groups.
Suitable secondary amines include, for example, Ν, Ν-dimethylamine, N, Ndiethylamine, Ν, Ν, -dipropylamine, N, N-diisopropylamine, Ν, Ν-dibutylamine, N-methyl-N-cyclohexylamine, N-methyl-N-phenylamine , N-methyl-N-benzylamine, or the like, and mixtures thereof. Ν, Ν-dimethylamine is cost effective and is particularly preferred.
Suitable secondary amines include ether amines. Thus, amines that are reaction products of ammonia or primary amines and an alkylene oxide, for example 0.1 to 20 molar equivalents of ethylene oxide, propylene oxide, or the like, can be used. The amine can be, for example, a monoalkylated derivative of a M series of polyether amine Jeffamina® (Huntsman product). In some cases of use of an ether, it may be necessary to mask any hydroxyl functionality as an appropriate derivative, both before and after the formation of the amide, in order to allow for the subsequent reduction of this amide.
Although fatty amides are made using a well-known process, the product mixture is unique because of the unconventional starting mixture of acid or ester derivatives. Reagents are typically reacted, with or without a catalyst under conditions effective to convert the acid, ester, or other starting derivative to an amide. The reaction temperature is typically within the range of 40 ° C to 300 ° C, preferably 50 ° C to 250 ° C, and more preferably 50 ° C to 200 ° C.
Reduction of the grease amide to provide a terminal amine is accomplished using well-known methods, including reactions with a hydride reducing agent (boranes, aluminum hydrides, borohydrides, or the like), or catalytic hydrogenation. Suitable reducing reagents include, for example, borane, borane dimethyl sulfide, sodium / iodine borohydride, lithium cyanoborohydride, aluminum hydride, aluminum and lithium hydride, diisobutylaluminum hydride, and the like. For additional examples, see R. Larock, Comprehensive Organic Transformations: A Guide to Functional Group Preparations (1989). pp. 432-434, and M. Smith and J. March, March's Advanced Organic Chemistrv. 5th ed. (2001), pp. 1549-1550.
In an alternative synthetic approach, grease amine is made by first reducing the acid derived from metathesis or ester derivative to
12/79 provide a fatty alcohol, followed by amination of the fatty alcohol. The metathesis-derived or ester-derived acid is reduced to a fatty alcohol using a metal hydride reagent (sodium borohydride, aluminum and lithium hydride, or the like), catalytic hydrogenation, or other well-known techniques to generate the fatty alcohol ( see, for example, U.S. Pat. No. 2,865,968; 3,193,586; 5,124,491; 6,683,224;
and 7,208,643, the teachings of which are incorporated herein by reference). Amination is then preferably performed in a single step through the reaction of fatty alcohol with ammonia or a primary or secondary amine in the presence of an amination catalyst. Suitable amination catalysts are well known. Catalysts comprising copper, nickel, and / or alkaline earth metal compounds are common. For suitable catalysts and processes for amination, see Pat. US No. 5,696,294; 4,994,622; 4,594,455; 4,409,399; and 3,497,555, the teachings of which are incorporated herein by reference.
In a preferred aspect of the invention, the grease amine is a grease amidoamine made by reacting a metathesis-derived C ₁₀ -C ₇ monounsaturated acid, octadecene-1,18-dioic acid or its ester derivatives with a tertiary amine substituted with aminoalkyl. This provides a product having tertiary amine functionality without the need to reduce a grease amide to a grease amine with a strong reducing agent. Suitable tertiary amines 20 substituted with aminoalkyl have a primary amino group at UriTtermw, an alkylene group, and a tertiary amine group at the other end of the molecule. The alkylene group is preferably a straight or branched C2-C6 diradical such as ethylene, propylene, butylene, or the like. Thus, suitable tertiary amines substituted with aminoalkyl include, for example, N, N-dimethyl-1,225 ethanediamine, N, N-dimethyl-1,3-propanediamine (DMAPA), N, N-diethyl-1,3propanediamine, N, N -dimethyl-1,4-butanediamine, and the like. DMAPA is particularly preferred. The primary amine group exhibits good reactivity with the acid or ester derivative, while the tertiary terminal amine is preserved in the product and provides a site for quaternization.
The relative amounts of secondary amine or tertiary amine substituted with aminoalkyl reacted with the acid or ester reagents depend on the desired stoichiometry and are left to the skilled person. In general, enough of the secondary amine (or tertiary amine substituted with aminoalkyl) is used to react with the majority of or all available ester or acid groups, i.e., preferably greater than 90%, and more preferably greater than 95% , among the available ester or acid groups.
13/79
The tertiary amine group of the grease amine or amidoamine grease is quaternized to provide a composition of quaternary ammonium, betaine or sulfobetaine. Suitable quaternization methods and reagents are well known in the art. Common reagents include, for example, 5 alkyl halides (methyl chloride, methyl bromide), dialkyl sulfates, carbonates, or phosphates (dimethyl sulfate, diethyl sulfate, dimethyl carbonate), benzyl chloride, acetyl chloride , ethylene oxide and others. Betaines are typically made by reacting grease amine or amidoamine with a ωhaloalkylcarboxylic acid or its alkali metal salt (eg sodium monochloroacetate 10 or potassium monochloropropionate) in the presence of a strong base. Sulphobetaines can be made by combining grease amine or amidoamine with epichlorohydrin, followed by sulfation with sodium bisulfite. An alternative procedure is highlighted below in which epichlorohydrin is first reacted with sodium bisulfite in the presence of sodium hydroxide, and the grease amine is added to that reaction mixture, followed by heating and neutralization, to provide sulfobetaine.

As the skilled person will recognize, products made according to the invention are typically mixtures of useful and trans isomers. Unless otherwise indicated, all structural representations provided here show only one trans isomer. The knowledgeable person will understand that this convention is used for convenience only, and that a mixture of cis and trans isomers is understood unless the context dictates otherwise. (The “C18” series of products in the examples below, for example, is nominally 100% trans isomers, while the “Mix” series is nominally mixtures of 80:20 trans / cis isomers). Structures shown often refer to a main product that may be accompanied by a lower proportion of other components or positional isomers. For example, reaction products from modified triglycerides are complex mixtures. As another example, sulfonation or sulfitation processes often provide mixtures of sultones, alkanesulfonates, and alkenesulfonates, in addition to isomerized products. 5 Thus, the structures provided represent likely or predominant products.
Charges may or may not be shown, but they are understood, as in the case of amine oxide structures. Counterions, as in quaternized compositions, are not usually included, but they are understood by a person versed from the context.

The mixture of quaternized grease amine or amidoamine grease product can be complex when the ester derivative reacted with the secondary amine or tertiary amine substituted with aminoalkyl is a modified triglyceride made by auto-metathesis of a natural oil and separation to remove olefins (see , for example, the MTG and PMTG products described below) or an unsaturated triglyceride made by cross-metathizing a natural oil and an olefin and separation to remove olefins (see, for example, the UTG and PUTG products described below). As is evident from the reaction schemes, DMAPA MTG and PMTG products include a C ₈ unsaturated quaternized diamidoamine as a major component, while UTG and PUTG products include a C ₁₀ unsaturated quaternized amidoamine and one or more unsaturated quaternized amidoamine components Cn to C17. (For example, 1-butene and 0 cross-metathesis reagent, as illustrated, results in an amidoamine unsaturated component C _2.). Other components of the product mixture are glycerin and saturated or unsaturated DMAPA quaternized amides. Despite the complexity, purification to isolate a particular species is often neither economical nor desirable for good performance.
Thus, in one aspect, the grease amidoamine is quaternized. Grease amidoamine is produced by reacting a tertiary amine substituted with aminoalkyl with a modified triglyceride made by auto-metathesis of a
18/79 natural oil. Auto-metathesis of natural oil provides a mixture of olefins and a modified triglyceride that is enriched in a Cis unsaturated diester component together with Cíe-C-is saturated diesters · The olefins are subjected to stripping, usually under reduced pressure and heat. When the modified triglyceride is reacted directly with DMAPA, a complex mixture results in which primary amino groups of DMAPA completely or partially displace glycerin from glyceryl esters to form amidoamine functionalities.
Products representing amidoamine below are made by reacting DMAPA with MTG-0 (modified soy oil triglyceride) or PMTG-0 (palm oil modified triglyceride) followed by quaternization. An example is MTG DMAPA sulfobetaine (“MTG-11”):

in grease is produced by reacting a tertiary amine substituted with aminoalkyl with an unsaturated triglyceride made by cross-metathizing a natural oil with an olefin. Cross-synthesis of natural oil and olefin provides a mixture of olefins and an unsaturated triglyceride that is rich in unsaturated esters Cio and C12 as well as saturated esters Ci6-Ci ₈ . The olefins are subjected to stripping, usually with heat and reduced pressure. When the unsaturated triglyceride is reacted directly with DMAPA, a complex mixture results in which primary amino groups of DMAPA completely or partially displace glycerin from the glyceryl esters to form amidoamine functionalities. Products representing amidoamine below are made by reacting DMAPA with UTG-0 (unsaturated triglyceride from cross-linked soy oil and 1-butene) or PUTG-0 (unsaturated triglyceride from cross-linked oil palm with 1butene), followed by quaternization. An example is the PUTG DMAPA quat product of dimethyl sulfate (“PUTG-13”):

The reaction to form the amidoamines from lower alkyl ester can be carried out under a spray of nitrogen or under vacuum to remove released alcohol. When glyceride esters are reactants, the released glycerin 5 does not need to be removed from the product. The reaction is considered complete when the residual glyceride content of the product reaches the desired level.
The quaternized fatty amines or amidoamines and their derivatives have unsaturation which can be sulfonated or sulphited if desired. Sulphonation is performed using well-known methods, including reaction of olefin 10 with sulfur trioxide. Sulphonation can optionally be conducted using an inert solvent. Non-limiting examples of suitable solvents include liquid SO2, hydrocarbons, and halogenated hydrocarbons. In a commercial approach, a falling film reactor is used to continuously sulfonate the olefin using sulfur trioxide. Other sulfonating agents can be used with or without the use of a solvent (eg, chlorosulfonic acid, fuming sulfuric acid), but sulfur trioxide is generally the most economical . Sultones which are the immediate reaction products of olefins with SO3, chlorosulfonic acid, and the like can subsequently be subjected to a hydrolysis reaction with aqueous caustic soda to allow mixtures of alkane sulfonates and hydroxyalkane sulfonates. Suitable methods for sulfonation of olefins are described in Pat. No. US3,169,142; 4,148,821; and Publ. Ped. Pat. No. US2010 / 0282467, the teachings of which are incorporated herein by reference.
Sulfitation is carried out by combining an olefin in water (and generally a co-solvent such as isopropanol) with at least one 25 molar equivalent of a sulphiting agent using well-known methods. Suitable sulfiting agents include, for example, sodium sulfite, sodium bisulfite, sodium metabisulfite, or the like. Optionally, a catalyst or initiator is included, such as peroxides, iron, or other free radical initiators. Typically, the reaction mixture is conducted at 15-100 ° C until the reaction is reasonably complete. Suitable methods for sulphiting olefins appear in

Example 1A: Cross Metathesis of Soy Oil and 1-Butene. A dry, clean stainless steel 5 gallon Parr reactor equipped with an immersion tube, suspended stirrer, internal cooling / heating coils, temperature probe, sampling valve and exhaust valve is purged with argon at 15 psig. Soybean oil (SBO, 2.5 kg, 2.9 mol, Costco, M _n = 864.4 g / mol, 85% by weight of unsaturation, sprinkled with argon in a 5-gal container for 1 h) added to the Parr reactor. Õ reactor is sealed, 20 and the SBO is purged with argon for 2h while cooling to 10 ° C. After 2h, the reactor is ventilated at 10 psig. The dip tube valve is connected to a 1-butene cylinder (Airgas, CP grade, 33 psig headspace pressure,> 99% by weight) and re-pressurized to 15 psig with 1-butene. The reactor is again vented to 10 psig to remove residual argon. The SBO is stirred at 350 rpm 25 and 9-15 ° C under 18-28 psig of 1-butene until 3 mol of 1-butene per SBO olefin bond is transferred to the reactor (~ 2.2 kg of 1 -butene over
4-5 h).
A toluene solution of [1,3-bis- (2,4,6-trimethylphenyl) -2imidazolidinylidene] -dichlororutene (3-methyl-2-butenylidene) (tricyclohexylphosphine) (C827, Matter) is prepared in a Fischer pressure vessel -Porter by dissolving 130 mg of catalyst in 30 g of toluene (10 mol ppm per mol of SBO olefin binding). The catalyst mixture is added to the reactor via the reactor dip tube by pressurizing the headspace inside the Fischer-Porter vessel with argon to 50-60 psig. The Fischer-Porter vessel and tube
22/79 immersion are rinsed with additional toluene (30 g). The reaction mixture is stirred for 2, Oh at 60 ° C and is then allowed to cool to room temperature while the gases in the headspace are vented.
After the temperature is released, the reaction mixture is transferred to a rounded bottom flask containing bleaching clay (B80 CG Pure-Flo® clay, product of the Oil-Dri Corporation of America, 2% w / w SBO, 58 g ) and a magnetic stir bar. The reaction mixture is stirred at 85 ° C under argon. After 2 hours, during which time any remaining 1-butene is allowed to vent, the reaction mixture cools to 40 ° C and is filtered through a glass frit.

Agricultural Glyphosates: Formulation Stability
Sample Preparation:
A 44.0% acid equivalent (ae) formulation is prepared first by loading glyphosate acid (486.2 g, 90.5% ae, Monsanto's product) into a 1L reaction vessel cooled with ice, equipped with a mixer and temperature probe. Deionized water (337.23 g) is added with a mixture to generate a glyphosate acid sludge. Potassium hydroxide pellets (176.58g, 86.6% KOH, Fisher) are slowly added so that the temperature of the solution does not exceed 50 ° C. The mixture is then allowed to cool to room temperature and is mixed until a clear glyphosate concentrate of 44% a.e. work. The pH of the concentrate is measured by preparing a 10% solution of the concentrate in deionized water and measuring it with a pH electrode. If the pH of the concentrate is between 4.2 and 4.4 the concentrate is used as is. If the pH needs to be adjusted, then glyphosate acid, KOH, and water are added in adequate amounts to yield the correct pH while maintaining the a.e level of 44% of the required concentrate.
Stability Test:
A test surfactant (5.0 g) is added to 45.0 g of the above glyphosate concentrate (44% a.e.) to yield a glyphosate formulation concentrate, ~ 39.6% a.e. (~ 540 g / L of a.e. K salts). This concentrate is mixed until a clear solution results. If no clear solution results, an aliquot of lauryl dimethyl amine oxide (LDMAO, ~ 50-60% active, Stepan product) is added to the surfactant to make a 90:10 blend of surfactant: LDMAO. This is then tested for stability as above. If it does not, the procedure of adding LDMAO to the surfactant continues until a reason is found that provides a stable glyphosate formulation. If no stable formulation can be made, the surfactant is considered incompatible with glyphosate. If a clear homogeneous solution results, the sample is divided into two and placed both in an oven at 54 ° C and a freezer at -10 ° C for two weeks. If there is no haze or separation, the formulation is considered stable at that temperature.
The control surfactant is a C12-C14 DMEA esterquat. This is prepared by reacting the mixture of lauric (C12) and myristic (C ₁₄ ) acids with N, N59 / 79
dimethylethanol amine (DMEA) at 140 ° C for 5h, then heating to 175 ° C to complete the reaction. Quaternization with methyl chloride in propylene glycol at 80 ° C at 40 psig in the usual manner provides the desired esterquat. The control surfactant provides a clear formulation at room temperature, but the formulation separates at -10 ° C. Addition of amine oxide in a ratio of 9: 1 to 1: 1 (control surfactant for amine oxide) is necessary to provide a desired stability with the control.
As shown in Table 4, twenty-two samples performed as well as or better than similar compounds in the stability test.

Antimicrobial products: active biocides
Biocide efficiency is assessed using the rapid selection assay, an ATP-based method that measures% relative bacterial elimination over a 5 min period. The control used is first generation ADBAC BTC 835 (benzildimethylammonium chloride). Test organisms: Pseudomonas aeruginosa and Staphylococcus aureas.
Twenty-four hour old test organism cultures are 10 prepared in Mueller Hinton broth and incubated. Samples are precisely weighed in deionized water or 400 ppm water to make a 1000 ppm solution taking into account the active level of the sample. The 24h culture is diluted to 10 vol%. to obtain a cell concentration of ~ 10 ⁷ cfu / ml (colony forming units per ml). Reagents are prepared using the 15 instructions provided in the BacTiterGlo ™ Microbial Cell Viability Assay kit (Promega product) and calibrated at room temperature for 15 min. Each type of formulation is dispensed (90 pL at 1000 ppm) in each row of a 96-well plate. White medium, that is, Mueller Hinton broth (10 pL) is dispensed in three replicated wells (1-3) to determine baseline, 20 while the organism to be tested (10 pL) is dispensed in nine replicated experimental wells ( 4-12). The timer is started, and the test plate (baseline and experimental) is rocked for 30s. At the end of an adequate contact time (for example 5 min or 10 min), an equal amount of BacTiter-GIo reagent mixture is added to each reaction mixture,
64/79 starting with the experimental samples and ending with the baseline samples. After swinging to ensure complete mixing, the relative luminescence units (RLUs) of each well are measured and recorded. The% elimination of 10 ⁷ cfu / ml after 5 min. contact time for each organism 5 in Dl or hard water is calculated from:
Elimination% = [1- (Ave. RLU of Wells Experimental - Ave. RLU of Wells baseline controls)] / 60000

Rough Surface Cleaners: Aqueous Degreasers
This test measures the ability of a cleaning product to remove greasy dirt debris from a white vinyl tile. The test is automated and 5 uses an industry standard Gardner direct washable apparatus. A camera and controlled lighting are used to make a real-time video of the cleaning process. The machine uses a sponge moistened with a known amount of the test product. As the machine rubs the sponge along the tile with debris, the video records the result, from which 10 a cleaning percentage can be determined. A total of 10 attempts are made using test formulation diluted with 1:32 water, and cleaning is calculated for each of attempts 1-10 to provide a profile of the cleaning efficiency of the product. The test sample is used as a component of different control formulations depending on whether it is anionic, amphoteric or non-ionic.
Anionic test samples:
A dilutable, neutral, all-purpose cleaner is prepared from propylene glycol n-propyl ether (4.0 g), butyl carbitol (4.0 g), sodium citrate (4.0 g), ethoxylated alcohol Bio-Soft® EC-690 (1.0 g, Stepan product), test sample 20 (0.29 g if 100% active material), and deionized water (for 100.0 g of solution).
The control sample for anionic testing replaces the test sample with
66/79
Stepanol® WA-Extra PCK (sodium lauryl sulfate, Stepan, 1.0 g, nominally 30% active material).
Nonionic and amphoteric test samples:
A dilutable, neutral, all-purpose cleaner is prepared from propylene glycol n-propyl ether (4.0 g), butyl carbitol (4.0 g), sodium citrate (4.0 g), Stepanol WA-Extra PCK (lauryl sulfate) sodium, 1.0 g), test sample (0.90 g if 100% active material), and deionized water (for 100.0 g of solution). The control sample for nonionic / amphoteric testing replaces the test sample with Bio-Soft EC-690 (ethoxylated alcohol, 1.0 g, nominally 90% active material 10).
Debris composition:
Tiles are exposed to debris with a particulate medium (50 mg) and an oil medium (5 drops). The particulate medium is composed of (in parts by weight) hyperhumus (39), paraffin oil (1), used motor oil (1.5), Portland cement 15 (17.7), silica 1 (8), molacca black (1.5 ), iron oxide (0.3), black clay bandy (18), stearic acid (2) and oleic acid (2). The oil medium is composed of kerosene (12), Stoddard solvent (12), paraffin oil (1), SAE-10 engine oil (1), Crisco® (1), olive oil (3), acid linoleic (3), and squalene (3).
Thirteen amphoteric samples (betaine, sulfobetaine) and five anionic 20 (sulfonate) perform as well as or better than the control in this test (see Tables 8 and 9). Note that C10-19 and C12-19 quat sulfonates are tested as replacements for Bio-Soft EC-690 because their total net charge is zero, although they are listed in Table 9 as an anionic test sample.

Rough surface cleaners: Sparkling glass and window cleaner
Control: Ammonyx® LO (lauramine oxide, 0.70 g, Stepan product, nominally 30% active) and Bio-Terge® PAS-8S (2.00 g, capriryl sodium sulfonate, Stepan product, nominally 38% of active) are combined with 5 isopropyl alcohol (2.50 g) and diluted to 100 ml with deionized water.
Test formulation: Test sample (0.21 g if 100% active material) and Bio-Terge PAS-8S (2.00 g) are combined with isopropyl alcohol (2.50 g) and diluted to 100 ml with water deionized.
Method: The test formulation is evaluated for clarity; only 10 clear formulations are evaluated in the lower film / lower stripe test. The test measures the cleaner's ability to leave a streak-free surface on a test mirror. The test formula is applied to a mirror in a controlled amount and rubbed with a standard substrate back and forth, allowing the spread product to dry. Once dry, the mirrors are inspected and evaluated by a two-person panel. Ratings of “better than,” “equal” or “worse than” the control are assigned. The formulation used here is used to evaluate amphoteric and non-ionic surfactants. Eight samples C16-13, C16-16, MTG-6, MTG-11, PMTG-6, PMTG-11, PUTG-6 and PUTG-11, had the same performance as the control in the test.
Cold water cleaning performance of compacting dirty laundry detergents
68/79
This method assesses the general cold water cleaning performance (55 ° F) (12.77 ° C) of a dirty laundry detergent formula that comprises a concentrated blend of anionic and non-ionic surfactants, a builder, C ₁₆ MES and an experimental sample. The formulations are prepared as described below. The experimental sample is tested for its ability to improve the overall cleaning performance over cocoamide DEA.
Preparation of Concentrated Blend:
Deionized water (90% of the total amount required) is first combined and mixed at 50 ° C with Bio-Soft® S-101 (10 dodecylbenzene sulfonic acid, 3.27% by weight, Stepan product). Sodium hydroxide (50% aq. Solution) is added to pH 11 (around 24% of the total amount of 4% by weight required). Citric acid (50% aq. Solution, 6.2% by weight) is added, followed by triethanolamine (3.45% by weight). Bio-Soft® EC-690 (laureth-7, 90% active, 27.8% by weight, Stepan product) is slowly added. The pH is adjusted to the range of 7.8 to 8.4, targeting 8.1 with the remaining aqueous sodium hydroxide solution. Sodium xylene sulfonate (40% active, 4.30% by weight) is added, followed by a preservative and the remaining deionized water (q.s. to 100% by weight).
Preparation of an ultra-detergent for dirty clothing with Cig MES and 20 blends:
Deionized water (q.s. to 100% by weight) is charged at 55-60 ° C. The concentrated mixture prepared above (58.0% by weight) is added while maintaining a temperature between 50 ° C and 60 ° C. MES Cie (87% active, 10.34% by weight) is slowly added and allowed to dissolve. The mixture is then allowed to cool to 35 ° C. The experimental sample or standard DEA cocamide (5.0% by weight) is then added slowly and the mixing continues until the batch is homogeneous.
Cold Water Cleanliness Assessment
Dirty laundry detergent (30 g, see Part A) is loaded into the washing machine, followed by dirty / stained fabric samples that are attached to pillowcases. Wash temperature: 55 ° F (12.77 ° C). Rinse: 55 ° F (12.77 ° C). The samples are detached from the pillowcases, dried, and ironed. Samples are scanned to measure L * a * b * values. which are used to calculate a debris removal index (IRS) for each type of sample. 35 Finally, the ASRI is calculated, which equals the SRI experimental sample minus the SRI of a predetermined standard dirty laundry detergent formula
69/79 (or control). When | ASRI | > 1, differences are noticeable to the naked eye. If the ASRI value is greater than or equal to 1, the sample is greater. If ASRI is less than or equal to -1, the sample is less. If ASRI is greater than 1 and less than 1, the sample is considered to be equal to the standard.
The following tissue samples exposed to standard debris / stains are used: dirt on cotton (DSC); bovine tallow (BT); kaolin clay and wool fat over polyester (WFK 30C); grass on cotton (GC); blueberry on cotton (BC); cocoa on cotton (EMPA 112); and blood / ink / milk on cotton (EMPA 116). At least three of each type of sample are 10 used per wash. Samples are stapled to the pillowcases for washing, and extra pillowcases are included to complete a six-pound load (2.72).
The same procedure is used to wash all pillowcases / samples, with care taken to ensure that water temperature, washing time, manner of addition, etc. are kept constant for the cold water washing process 15. When the cycle is complete, samples are removed from the pillowcases, dried over low heat in a rack and pressed briefly with a dry iron.
A Hunter Labscan® XE spectrophotometer is used to determine the L * a * b * values to calculate the SRI for each type of sample, and the stain removal index (SRI) is calculated as follows:
SRI = 100 - y / (L * llmpo - L * washed) ² + (a * clean - a * washed) ² + (b * clean - b * washed) ²
ASRI = SRI ^sample— Standard SRI
As shown in Table 10, two of the test samples perform as well as or better than cocamide DEA when evaluated for cold water cleaning performance.

This method assesses the cleaning enhancing ability of an experimental sample when used as an additive in an economical dirty laundry detergent formulation that contains neutralized 5 dodecylbenzene sulfonic acid, a nonionic surfactant such as an ethoxylated synthetic C12C15 alcohol (7 EO ), citric acid, monoethanolamine, triethanolamine, and a preservative. The experimental sample is tested for its ability to improve overall cleaning performance at 1% solids level compared to Ammonyx® LO (lauramine oxide, standard intensifier, Stepan product). 10 Dirty laundry detergent formula (46 g) is loaded into the washing machine, followed by debris / stained fabric samples that are attached to the pillowcases. Wash temperature: 90 ° F (32 ° C). Rinse: 70 ° F (21 ° C). The samples are detached from the pillowcases, dried and ironed.
The economical dirty laundry detergent with intensifier is prepared 15 from neutralized dodecylbenzene sulfonic acid (NaLAS, Bio-Soft® S-101, Stepan, 33.9% active, 41.3% by weight), Bio-Soft® N25-7 (fatty alcohol ethoxylate, Stepan product, 5.00% by weight), intensifier (both the experimental sample and Ammonyx LO, which is 30% active, 3.33% by weight, citric acid (50% of aq. solution, 1.00% by weight), monoethanolamine (1.00% by weight), 20 triethanolamine (1.00% by weight), and deionized water plus preservative (balance to 100% by weight).
The formulation is made by loading 90% of the total amount of water to 50 ° C, then adding in order, with mixture, citric acid solution, monoethanolamine, triethanolamine, neutralized sulfonic acid, Bio-Soft N25-7, and 25 booster. The pH is adjusted to 9.5 with 25% aq. of NaOH, and then preservative and water balance are added.
The following tissue samples exposed to standard debris / stains are used: dirt on cotton (DSC); dirt tallow on cotton / polyester (DSCP); bovine lard (BT); clay on cotton (CC); clay 30 on cotton / polyester (CCP); grass on cotton (GC); red wine on cotton (RWC); blueberry on cotton (BC); coffee on cotton (COFC); cocoa on cotton (EMPA 112); blood / ink / milk on cotton (EMPA 116); and cotton makeup (EMPA 143). At least three of each type of sample are used per wash. Samples are stapled to the pillowcases for washing, 35 and extra pillowcases are included to complete a six pound load (2.72).

Sparkling Poco de Gás: Dynamic Batch Test
In this procedure, surfactant, brine, and / or test condensate are added to a column and then stirred with nitrogen to produce foam.
The weight% of foam carried along the column after 5 min. is a measure of the performance of the test sample. Results are collected as a function of the brine composition, surfactant concentration, and percentage of condensate present in the solution.
Pickles are prepared at 12.5% and 25% total dissolved solids (TDS). Pickles are an 80:20 ratio of NaCI to CaCb The density of 12.5% TDS is 1.087 g / ml and the density of 25% TDS is 1.184 g / ml. Brine solutions are filtered to eliminate particulates.
72/79
Surfactant samples are tested at 5000, 2000,1000, and 500 parts per million assets in each of the brine solutions listed above. A test solution consists of brine, surfactant, and condensate when applicable. The equation below indicates how much surfactant is needed based on the level of assets and the density of the brine used.
Surfactant (g) = desired ppm Γ Total Sol'n (g)
Brine Density (g / ml) - x --------- ^: ---------------'------ 1000 active

This sample calculation shows how much of a 45% active surfactant is needed to make a 5000 ppm solution in 12.5% TDS brine:
5QQQ ppm 1000
238,053g
£ 1,087g / m
0.45 of active 1000 = 2.43 g of surfactant in 238.053 g of 12.5% TDS brine
The 5000 ppm solution is used to make a 2000 ppm solution, which is diluted to make a 1000 ppm solution, and so on. When condensate is included, the desired active level in the brine must be such that the active level in the test solution remains constant with the varying amounts of condensate present. For example, when making a 5000 ppm solution with 20 10% condensate, the brine / surfactant solution will actually be 5556 ppm, so the most condensed solution will be -5000 ppm. When testing how well a product handles condensate, either 10% or 20% is added to the solution. This is done for both brine solutions at each concentration level.
The condensate used is a lower aromatic mineral turpentine, Exxsol® D25 40 (d = 0.7636 g / ml), product of ExxonMobil. The desired amount of condensate is added to the column after the brine / surfactant solution is added. Nitrogen is fed through a glass frit at the bottom of the column and a mass flow controller is used to feed standard 14 cubic feet per hour. DataStudio software (from Pasco) and a balance are used to measure the amount of foam collected. Weight is recorded every second over the course of a 10-minute period. The% of liquid carried over as foam after 5 min. for each brine solution, each% of condensate level is reported in Table 12.

As shown in Table 12, eight of the test samples performed well or better than the control when evaluated as potential sparklers from gas wells.

Personal Care: Cleaning Application
Tests of mechanical foam balance and viscosity are used to assess the probable value of a particular surfactant as a secondary surfactant in personal care cleaning applications.
All experimental samples are evaluated for their performance versus a control (be it cocamidopropylhydroxysultaine or cocamidopropyl betaine).
Viscosity curves are generated by preparing aqueous solutions of dilution of the test or control material with 12% lauryl (1) sodium ether 10 (SLES-1), then measuring viscosity using a Brookfield DV viscometer -1+. Sodium chloride is added incrementally (1-3% by weight) and viscosity is recorded as a function of increasing NaCI concentration. A “good” result is a curve that shows a viscosity construction comparable to the control sample. A “15” rating indicates that the sample builds viscosity more quickly than the control.
Foaming properties are assessed using a mechanical foam agitation test. Sample solutions (calculated at 0.2% of the total active surfactant material) are therefore made up of aqueous solutions using 20 ° C tap water. A 100, Og portion of the solution is carefully transferred to a 500 ml graduated cylinder. Castor oil (2.0 g) is added. The cylinder is capped and mechanically inverted ten times, then allowed to adjust for 15 seconds. Foam height is recorded. After 5 min, foam height is recorded again. The experiment is repeated without castor oil. In a set of experiments, the cleaning base contains SLES-1 both in the experimental and in the control. In a second set of experiments, the cleaning base contains another widely used anionic surfactant, that is, a mixture of sodium methyl 2-sulfolaurate and disodium 2-sulfolaurate, instead of SLES-1. A “good result is recorded when the solution containing the test material results in a foam height that is within +/- 25 ml of the control run. Results> 25 ml of control obtain a superior classification; results <25 ml of the control are classified as inferior.
Ten test materials, identified in Table 13, show good overall performance in viscosity and foam tests ._______________________

Method for Determining Foam Reinforcement Benefit
Foam volume, which signals “cleanliness” to consumers, is a desirable attribute in an antibacterial soap. As cationic antibacterial actives 5 are not compatible with anionic surfactants (the best foaming agents), achieving sufficient foam volume with them is challenging. The method below identifies surfactants that provide more foam volume than cocamidopropyl betaine (active / active bases) in an antibacterial soap base. Formulation: deionized water (qs to 100% by weight), 10 cocoglycoside (3.0% by weight), lauramine oxide (3.0% by weight), benzalkonium chloride (0.1% by weight), and test molecule or cocamidopropyl betaine (3.0 % by weight).
Solutions are prepared by combining ingredients in the order prescribed above, stirring with a stir bar or gently mixing 15 using an overhead stirrer or manually using a spatula. Heat can be applied if the test molecule is a solid at room temperature. Mixing is maintained to ensure a homogeneous solution. The pH is adjusted to
6.5 +/- 0.5.
Test and control solutions are compared, with and without castor oil 20 2%, to 0.2% of total surfactant active concentration (2.22 g of solution for
100 ml with Lake Michigan tap water, ~ 150 ppm Ca / Mg hardness) for foam volume using the cylinder inversion test. Initial and delayed measurements (5 min.) Are taken.
Classification system: Superior: a result> 25 ml over the cocamidopropyl betaine control 25 in both oil and non-oil systems. Good: a result within 25 ml of the cocamido-propyl betaine control in both oil and non-oil systems. Lower: a result> 25 ml below
76/79 of that of cocamidopropyl betaine control in both oil and non-oil systems.

Hair Conditioners: Procedure for Assessing 10 Wet Compatibility
Strands of hair (10 ”length, 2-3 g) are prepared using a uniform and consistent hair type (double bleached, blond). The strands are collectively washed with shampoo with a 15% solution of active sodium lauryl sulfate. Care is taken to avoid excessive embarrassment during shampooing. The wicks are rinsed clean with tap water at 40 ° C. The process is repeated to simulate double application of shampoo. The strands are separated and tangled for testing. The test conditioner preparation (2.0 cm ³ ) is applied to each damp wick, cleaned using a syringe. The base conditioner contains cetyl alcohol (2.0%), hydroxyethyl cellulose (0.7%), 20 cetrimonium chloride (1.0%) and water (100% qs). Test samples are formulated as a 2% by weight (active) additive for the base conditioner.
The conditioner is processed by touching fingers down for a minute on the hair. The wicks are rinsed thoroughly under 40 ° C 25 tap water. Excessive water is squeezed from each strand to simulate towel drying. The hair is combed, first, in the wet state. It is assessed that it is easy to comb through the test samples and base conditioner, and qualitative ratings are assigned to the test samples compared to results with base conditioner only.
77/79 .V * For the quaternized compositions tested, the classification system is as follows: “superior” is a wet hairstyle enhancement above the conditioner used as a test control; “Equal” is a wet hairstyle comparable to the conditioner used as a test control; and “bottom” is 5 wet hairstyle worse than the conditioner used as a test control.
One sample, Mix-44, is superior to the base conditioner in this test, and two samples, C16-10 and PUTG-13, perform the same for the control.

Polarization resistance is performed in diluted NACE brine (3.5% by weight NaCI; 0.111% by weight CaCl2.2H ₂ O; 0.068% by weight MgCI ₂ * 6H ₂ O) under sweet conditions (pulverized CO ₂ ) at 50 ° C. The functional electrode is cylindrical, made of C1018 iron and rotates at 3000 rpm. The opposite electrode is a platinum wire. The reference is a calomel electrode with an internal salt bridge.
A baseline corrosion rate is established over at least a 3 hour period. Once the baseline has been established, the corrosion inhibitor is injected and data is collected for the remainder of the test period. The desired inhibitor concentration is 0.00011-0.0010 meq / g active. Software details: initial delay is 1800 s with 0.05 mV / s stability; range: -0.02 to + 0.02V; scanning speed: 0.1 mV / s; sample period: 1 s; data collection: ~ 24h. The final corrosion range is an average of the last 5-6 hours of data collection. Protection range is calculated from:
Protection Range = (Initial Protection Range [without inhibitor] - Final Protection Range [with inhibitor!) * 100
Initial Protection Range [without inhibitor]
As shown in Table 16, eight of the samples tested show overall performance as corrosion inhibitors that are equal to or exceed that of the control.

Oilfield Products: Paraffin Dispersant
Asphaltene Selection Test
During acid stimulation of an oil well, a mixture of HCI, HF, and corrosion inhibitor is pumped down a well, allowed to stand, and then pumped out. During the transfer of the acid, small amounts of iron chloride are developed in the acidic solution. Once the mixture of acid dissolves on scales and deposits in the diameter of the well, crude oil begins to flow and mixes with the acid solution in the well. Crude oil can solidify after acidification, and asphaltenes have been associated with the problem. Therefore, dispersants are commonly added to the acid to prevent solidification.
Test method:
A stock solution of acid contaminated with iron is made by adding 1% FeCI ₃ to a 15% HCI acid solution. The sample dispersant to be tested (0.2% by weight) is added to the acid stock solution (7.5 ml). A 15 ml ampoule is charged with the mixture of acid / dispersant and crude oil (2.5 ml), and the ampoule is shaken vigorously for 30 s. The initial appearance is recorded. After standing at room temperature for 1 h, the appearance is noticed again. The ampoule is placed in an oven (50 ° C) for 24 hours and its appearance is recorded. The ampoule is allowed to cool to room temperature and the appearance is noticed again. Finally, after 24 hours at room temperature, the appearance is noticed again. A white sample containing crude oil and acidic solution, but no dispersant is run. A control sample containing trimethylammonium chloride starch soy amine as the dispersant is run as well. Yet another sample is run containing a 1: 1 mixture of test dispersant and trimethylammonium chloride starch soy amine.
One sample, C18-65, provides performance that is equal to the control in this test, while C18-27 demonstrates superior performance.
Performance as a Sparkling or Foam Additive for Special Sparkling Applications,. f
79/79
Special sparkling applications include (among others) gypsum, concrete, and fire-resistant foams. The tests below evaluate the foam stability when the sample is used as the primary sparkling wine and also evaluate the sample performance as an additive when used as a foam stabilizer, enhancer or destabilizer.
Particularly from gypsum, for which adjustment times are fast on commercial production lines, a desirable foam additive helps to control the bubble coalescence to provide a larger bubble within a predicted time frame. Preferably, foam destabilization occurs at the end of the first minute in the tests below. These compositions are identified as good gypsum foam destabilizing performers in Table 17 because they allow this balance to be effectively achieved.
Foam stability: Drainage method
Surfactant solutions (0.4% by weight of active material) are prepared by mixing surfactant with water having variable hardness (water of 342 ppm hardness or 100 ppm CaSo4 water). Surfactant solution (100 ml) is carefully transferred to a stainless steel mixing cup, then mixed at high speed (27K rpm) using a Hamilton Beach mixer for 10s. The contents are quickly poured into a cylinder ---------------- graduated from 100ml to the 100ml mark, and the timer starts immediately. The amount of liquid adjusting in the cylinder is recorded every 15 seconds for 4 minutes. Less drained liquid indicates more foam stability.
Foam Stability: Foam Half Life
A sample of surfactant solution prepared as described above (100g) is mixed at high speed for 30s. The mixture is quickly poured into a 1000ml graduated cylinder and a timer is started immediately. Initial foam height is recorded. When 50 ml of liquid appears in the cylinder, the time of foam height is recorded as the foam half-life (in seconds) and foam height in half-life (in mL), respectively ._______________________________________________________
