专利说明:

“COMPOSITION, DETERGENT, CLEANING COMPOSITION, DISINFECTANT OR BLeach, GRANULE, PROCESS FOR THE STAINING OF STAINS OR DIRT IN TEXTILE MATERIALS, AND, USE OF COMPOUND” [001] The present invention concerns specific acylhydrazone compounds, their use as oxidation catalysts and a process to remove stains and dirt on textiles and hard surfaces. The compounds are replaced by a specific cyclic ammonium group adjacent to the acyl group. Additional aspects of the invention are compositions or formulations that comprise such compounds.
[002] Metal complex catalysts with hydrazide ligands have generally been described as oxidation catalysts, for example, in DE 196 39 603. However, the disclosed compounds are not active enough.
[003] In WO 2009/124855, metal complex compounds have hydrazide ligands, preferably with electron withdrawal groups adjacent to the acyl group are described. The respective acylhydrazone ligands and their use are also described. The present compounds differ from those described in WO 2009/124855 in being replaced by a specific cyclic ammonium group adjacent to the acyl group. This specific substitution pattern guarantees a substantially higher bleach activity compared to the prior art complexes or ligands.
[004] The present compounds are used especially for intensifying the action of H2O2 or peroxides, for example, in the treatment of textile materials, without, at the same time, causing any estimated damage to fibers and dyes. There is also no estimated damage to fibers and dyes if these compounds are used in combination with an enzyme or a mixture of enzymes.

2/52 [005] The present compounds can also be used as the catalysts for oxidation using molecular oxygen and / or air, that is, without peroxide compounds and / or peroxide-forming substances. The bleaching of the tissue can happen during and / or after the treatment of the fiber with the formulation, which comprises the compounds.
[006] The compounds do not cause any odor during use and are significantly more efficient as bleach catalysts compared to the corresponding open chain tertiary amines.
[007] Metal ions, such as aluminum, zinc, manganese, titanium, iron, cobalt, nickel or copper, for example, Al (III), Zn (II), Mn (II) (III) - (IV) - (V), Cu (I) - (II) - (III), Fe (I) - (II) - (III) - (IV), Co (I) - (II) - (III), Ni (I ) - (II) (III), Ti (II) - (III) - (IV) or, for example, Mn (II) - (III) - (IV) - (V), Cu (I) - (II ) - (III), Fe (I) - (II) - (III) - (IV) and Co (I) - (II) - (III) may be present during the textile material treatment process but are not required for the improved targeting effect.
[008] Bleaching agents containing peroxide have been used in washing and cleaning processes. These have an excellent action at a liquid temperature of 90 ° C and above, but their performance decreases noticeably at lower temperatures. Various transition metal ions added in the form of suitable salts and coordination compounds containing such cations are known to activate H2O2. In that way, it is possible that the bleaching effect, which is unsatisfactory at lower temperatures, of H2O2 or precursors that release H2O2 and other peroxo compounds, is increased.
[009] The purpose of the present invention is, therefore, to provide improved metal-free catalysts for oxidation processes that satisfy the above requirements and, especially, intensify the action of peroxide compounds in most varied fields of application without causing any estimated damage .

[0033] The compounds of formula (1) are useful as catalysts for oxidation reactions, for bleaching stains and dirt on textiles or for cleaning hard surfaces.
[0034]
Therefore, another aspect of the invention is a composition that comprises
a) H2O2 or a precursor to H2O2 and
b) a compound of formula (1) as described above.
[0035] The amount of component b), composed of formula (1), in the composition can vary from 0.00001% by weight to 1% by weight, preferably from 0.0001% by weight to 0.1% by weight, based on weight of the total composition.
Petition 870180071085, of 08/14/2018, p. 19/76
10/52 [0036] In many cases in the composition as described above, additional bleach activators are present. Suitable bleach activators are summarized below.
[0037] The amount of bleach activator in the composition can vary from 0.1% by weight to 12% by weight, preferably from 0.5% by weight to 10% by weight, based on the weight of the total composition.
This can be of advantage when the composition as described above optionally contains one or more metal chelating agents (scavengers), such as hydroxyethyldiphosphonate (HEDP). More generally, chelating agents suitable for use herein can be selected from the group consisting of amino carboxylates, amino phosphonates, polyfunctional substituted aromatic chelating agents and mixtures thereof. Other chelating agents suitable for use in this are the commercial DEQUEST series and chelators from Nalco, Inc.
[0039] Aminocarboxylates useful as optional chelating agents include ethylene diaminetetracetates, N-hydroxyethylethylenediaminetriacetates, nitrilotriacetates, ethylenediamine tetraproprionates, triethylenetetraaminoexacetates, diethylenetriamine-penta-acetates and these ethanalyglycosides and ethanololdines.
[0040] Aminophosphonates are also suitable for use as chelating agents in the compositions of the invention when at least low levels of total phosphorus are permitted in detergent compositions and include ethylene diaminetetraquis (methylene phosphonates).
[0041] Additional biodegradable scavengers are, for example, amino acid acetates, such as Trilon M (BASF) and Dissolvine GL (AKZO), as well as asparaginic acid derivatives, such as Baypure CX. [0042] Preferably, the aminophosphonates do not contain alkyl or alkenyl groups with more than about 6 carbon atoms.
Petition 870180071085, of 08/14/2018, p. 20/76
11/52 [0043] A highly preferable biodegradable chelator for use here is ethylenediamine disuccinate (“EDDS”).
[0044] The following chelating agents (scavengers) are preferred:
citric acid, oxalic acid, methyl-glycine-diacetic acid (MGDA), ethylenediamine-N, N'-disuccinic acid (EDDS), 1-hydroxy ethylidene-1,1diphosphonic acid (HEDP).
[0045] If used, these selective transition metal chelating or sequestering agents, in general, will be present from about 0.001% by weight to about 10% by weight, more preferably from about 0.05% by weight to about 1% by weight, based on the weight of the total composition. [0046] Component a) of the composition can be H 2 O 2 , a precursor of
H 2 O 2 or a peroxide-forming substance. H2O2 precursors are preferred, such as peroxides or peracids summarized below.
[0047] As precursors of H 2 O 2 peroxides come into consideration. That is, each compound that is capable of producing hydrogen peroxide that is capable of producing hydrogen peroxide in aqueous solutions, for example, the organic and inorganic peroxides known in the literature and commercially available that targets textile materials at conventional washing temperatures, for example example, 10 to 95 ° C.
[0048] Preferably, however, organic peroxides are used, for example, persulfates, perborates, percarbonates and / or persilicates. These are typically used in an amount of 2 to 80% by weight, preferably 4 to 30% by weight, based on the weight of the composition.
[0049] Typically, the compound of formula (1) is present in the composition in an amount of 0.05 to 15% by weight, preferably 0.1 to 10% by weight, based on the weight of the total composition.
[0050] Examples of suitable inorganic peroxides are sodium perborate tetrahydrate or sodium perborate monohydrate, sodium percarbonate, inorganic peroxyacid compounds, such as, for example,
Petition 870180071085, of 08/14/2018, p. 21/76
12/52 example, potassium monopersulfate (MPS). If organic or inorganic peroxyacids are used as the peroxygen compound, their amount will normally be in the range of about 2 to 80% by weight, preferably 4 to 30% by weight, based on the weight of the composition.
[0051] Organic peroxides are, for example, mono- or polyperoxides, urea peroxides, a combination of a C1-C4 alkanol oxidase and C1-C4 alkanol (such as methanol oxidase and ethanol as described in WO95 / 07972), alkyl hydroxy peroxides, such as cumene hydroperoxide and t-butyl hydroperoxide.
[0052] Peroxides can be a variety of crystalline forms and have different water contents and these can also be used together with other inorganic or organic compounds in order to improve their storage stability.
[0053] As oxidants, peroxy acids can also be used.
An example are organic mono peracids of the formula or iT co-om in which
M means a hydrogen or a cation,
R 19 means unsubstituted C 1 -C 18 alkyl; substituted C 1 -C 18 alkyl; unsubstituted aryl, substituted aryl; - (C 1 -C 6 alkylene) -aryl, where the alkylene and / or the alkyl group can be substituted and phthalimidoalkylene C 1 -C 8 , in which the phthalimido group and / or the alkylene group can be substituted.
[0054] The preferred mono organic peroxy acids and their salts are those of the formula o
r ^ c-o-om where
M stands for hydrogen or an alkali metal and
Petition 870180071085, of 08/14/2018, p. 22/76
13/52
R'i9 means C1-C4 alkyl; phenyl; C1-C2 alkylene-phenyl or C1-C8 phthalimidoalkylene.
[0055] CH 3 COOOH and its alkaline salts are especially preferred.
[0056] Also especially preferred is peroxy hexanoic ε-phthalimido acid and its alkaline sausages and its alkaline salts.
[0057] Diperoxy acids, for example, acid, are also suitable
1,12-diperoxidodecanedioic acid (DPDA), 1,9-diperoxiazelaic acid, diperoxybasilic acid, diperoxysebasic acid, diperoxyisophthalic acid, 2decildiperoxybutane-1,4-diotic acid and 4,4'-sulfonylbisperoxybenzoic acid.
[0058] In some cases, the use of an additional bleach activator may be advantageous.
[0059] The term bleach activator is often used as a synonym for peroxyacid bleach precursor. All of the peroxy compounds mentioned above can be used alone or in conjunction with a peroxyacid bleach precursor.
[0060] Such precursors are the corresponding carboxyacids or the corresponding carboxyanhydride or the corresponding carbonyl chloride or amides or esters, which can form the peroxyacids in perhydrolysis. Such reactions are commonly known.
[0061] Peroxyacid bleach precursors are known and widely described in the literature, such as in British Patents 836988; 864,798; 907,356; 1,003,310 and 1,519,351; German Patent 3,337,921; EP-A0185522; EP-A-0174132; EP-A-0120591 and U. S. Patents No. 1,246,339; 3,332,882; 4,128,494; 4,412,934 and 4,675,393.
[0062] Suitable bleach activators include bleach activators, which carry unsubstituted or substituted O- and / or N-acyl groups and / or benzoyl groups. Preference is given to polyacetylated alkylenediamines, especially tetraacetylethylenediamine (TAED); acetylated glycolurils, especially tetraacetyl glycol urea (TAGU), N, N-diacetyl-N, N Petition 870180071085, from 08/14/2018, p. 23/76

R 21 O (10) where R22 is a sulfonate group, a carboxylic acid group or a carboxylate group and where R 21 is straight or branched (C 7 -C 15 ) alkyl, especially activators known under the names SNOBS, SLOBS and DOBA; acylated polyhydric alcohols, especially triacetin, ethylene glycol diacetate and 2,5-diacetoxy-2,5-di-idrofuran and also acetylated sorbitol and mannitol and acylated sugar derivatives, especially pentaacetylglucose (PAG), sucrose polyacetate (SUPA), penta -acetylfructose, tetraacetylxylose and octaacetillactose as well as optionally glucamine Nakylated acetylated and gluconolactone. It is also possible to use the combinations of conventional bleach activators known from German Patent Application DE-A-44 43 177. Nitrile compounds that form acids with peroxides are also considered as bleach activators.
[0063] Another useful class of peroxyacid bleaching precursors is that of cationic precursors, i.e. peroxyacid substituted by quaternary ammonium as disclosed in US Patent No. 4,751,015 and 4,397,757, in EP-A0284292 and EP-A-331,229. Examples of peroxyacid bleach precursors of this class are: 2- (N, N, N-trimethyl ammonium) ethyl sodium 4-sulfonphenyl carbonate - (SPCC), N-octyl chloride, N, N-dimethyl-N10 carbophenoxy decyl ammonium - (ODC), 3- (N, N, N-trimethyl ammonium carboxylate)

15/52 propyl sodium-4-sulfophenyl carboxylate and N, N, N-trimethyl ammonium toluyloxy benzene sulfonate.
[0064] Another special class of bleach precursors is formed by cationic nitriles as disclosed in EP-A-303,520, WO 96/40661 and in European patent specification No. 458,396, 790244 and 464,880. These cationic nitriles also known as nitrile quats have the formula x -

Petition 870180071085, of 08/14/2018, p. 41/76
[00129] Another group of acceptable dispersants are organic dispersing polymers, such as polyaspartate.
[00130] Depending on whether a greater or lesser degree of density is required, filler materials may also be present in immediate dishwashing detergent formulations, more preferably automatic dishwashing detergent formulations. These include sucrose, sucrose esters, sodium sulfate, potassium sulfate, etc., in amounts up to about 70% by weight, preferably from 0.1% by weight to about 40% by weight of detergent washing formulations. dish, more preferably automatic dishwashing detergent formulations. The preferred filler is sodium sulphate, especially in good grades having lower levels of trace impurities.
[00131] The sodium sulfate used in this preferably is of sufficient purity to ensure it is not reactive with bleaching; it can also be treated with low levels of scavengers, such as phosphonates or EDDS in the form of magnesium salt. It is noted that the preferences, in terms of sufficient purity to prevent bleaching of the decomposition, also apply to the pH adjusting component ingredients, especially including any silicates used in it.

Petition 870180071085, of 08/14/2018, p. 42/76
33/52 [00133] Many dish washing detergent formulations, more preferably automatic dish washing detergent formulations in this will be buffered, that is, these are relatively resistant to the pH drop in the presence of acidic soils. However, other compositions in these can exceptionally have a low buffering capacity, or can be substantially non-buffered. Techniques for controlling or varying the pH at the recommended usage levels more generally include using not only buffers, but also additional alkalis, acids, pH jump systems, double compartment containers, etc. and are well known to that person skilled in the art.
[00134] Certain dishwashing detergent formulations, more preferably automatic dishwashing detergent formulations, comprise a pH adjustment component selected from the water-soluble alkaline inorganic salts and water-soluble organic or inorganic builders. The pH adjustment components are selected so that when the dishwashing detergent formulation, more preferably automatic dishwashing detergent formulation is dissolved in water at a concentration of 1,000-5,000 ppm, the pH remains in the range above about from 8, preferably from about 9.5 to about 11. The preferred non-phosphate pH adjustment component can be selected from the group consisting of:
(i) sodium carbonate or sesquicarbonate;
(ii) sodium silicate, preferably water sodium silicate having a SiO2: Na2O ratio of about 1: 1 to about 2: 1, and mixtures thereof with limited amounts of sodium metasilicate;
(iii) sodium citrate;
(iv) citric acid;
(v) sodium bicarbonate;
(vi) sodium borate, preferably sodium borate;
Petition 870180071085, of 08/14/2018, p. 43/76
34/52 (vii) sodium hydroxide; and (viii) mixtures of (i) - (vii).
[00135] The preferred embodiments contain low levels of silicate (i.e. from about 3% by weight to about 10% by weight SiO 2 ). [00136] Illustrative of the highly preferred pH adjustment component systems of this specialized type are the binary mixtures of granular sodium citrate with anhydrous sodium carbonate and mixtures of three components of granular trihydrate sodium citrate, citric acid monohydrate and carbonate anhydrous sodium.
[00137] The amount of the pH adjusting component in the compositions used for automatic dish washing is preferably from about 1% by weight to about 50% by weight of the composition. In a preferred embodiment, the pH adjusting component is present in the composition in an amount of about 5% by weight to about 40% by weight, preferably from about 10% by weight to about 30% by weight . [00138] For the compositions in this having a pH between about 9.5 and about 11 of the initial wash solution, particularly the embodiments of the preferred automatic disc washing detergent formulations comprise, by weight of the detergent wash detergent formulations automatic discs, from about 5% by weight to about 40% by weight, preferably from about 10% by weight to about 30% by weight, more preferably from about 15% by weight to about 20% by weight sodium citrate of about 5% by weight to about 30% by weight, preferably from about 7% by weight to 25% by weight, more preferably from about 8% by weight to about 20% by weight of sodium carbonate.
[00139] The essential pH adjustment system can be complemented (that is, by improved sequestration in hard water) by other optional detergent builder salts selected from non-phosphate detergent builders known in the art, which includes the various ammonium borates soluble
Petition 870180071085, of 08/14/2018, p. 44/76
35/52 in water, alkali metal, or substituted ammonium, hydroxysulfonates, polyacetates and polycarboxylates. Preferred are alkali metals, especially sodium, salts of such materials. Non-phosphorous, water-soluble organic builders can be used for their sequestering properties. Examples of polyacetate and polycarboxylate builders are the sodium, potassium, lithium, ammonium and ammonium salts substituted for ethylenediamine tetraacetic acid; nitrilotriacetic acid, monosuccinic tartrate acid, disuccinic tartrate acid, oxidisuccinic acid, carboxymethoxysuccinic acid, melitic acid and sodium benzene polycarboxylate salts. Additional biodegradable builders are, for example, amino acid acetates, such as Trilon M (BASF) and Dissolvine GL (AKZO), as well as derivatives of asparaginic acid, such as Baypure CX. [00140] Detergent formulations can take a variety of physical forms such as, for example, powder granules, tablets (tabs), gel and liquid. Examples of these include, inter alia, conventional high-performance post-detergents, super-compact high-performance post-detergents and tabs. An important physical form is the so-called concentrated granular form, which is added in a washing machine.
[00141] Also of importance are detergents called compact or supercompact. In the field of detergent manufacturing, there is a direction close to the production of such detergents that contains an increased amount of the active substances. In order to minimize energy consumption during the washing procedure, compact or supercompact detergents needed to act effectively at low washing temperatures, for example, below 40 ° C, or at room temperature (25 ° C). Such detergents usually contain only minor amounts of fillers or substances, such as sodium sulfate or sodium chloride, required by detergent manufacturing. The total amount of such substances is usually 0 to 10% by weight, especially 0 to 5%
Petition 870180071085, of 08/14/2018, p. 45/76
36/52 by weight, more especially from 0 to 1% by weight, based on the total weight of the detergent formulation. Such (super) compact detergents usually have a volume density of 650 to 1000 g / l, especially 700 to 1000 g / l and more especially 750 to 1000 g / l.
[00142] Detergent formulations can also be in the form of tablets (tabs). The advantages of tabs lie in the case of dispersing and the convenience in handling. Tabs are the most compact form of the solid detergent formulation and usually have a volumetric density of, for example, 0.9 to 1.3 kg / liter. To achieve rapid dissolution, such tabs usually contain special dissolution aids:
- carbonate / hydrogen carbonate / citric acid as effervescent;
- disintegrators, such as cellulose, carboxymethyl cellulose or cross-linked polyvinylpyrrolidone;
- Quickly dissolved materials, such as sodium acetates (potassium), or sodium citrates (potassium);
- Rigid coating agents, soluble in water, quickly dissolved, such as dicarboxylic acids.
[00143] Tabs can also comprise combinations of such dissolution aids.
[00144] The detergent formulation can also be in the form of an aqueous liquid containing from 5% by weight to 50% by weight, preferably from 10% by weight to 35% by weight, of water or in the form of a non-liquid non-liquid containing more than 5% by weight, preferably from 0% by weight to 1% by weight of water. Aqueous non-liquid detergent formulations may comprise other solvents such as carriers. Primary or secondary low molecular weight alcohols, for example, methanol, ethanol, propanol and isopropanol, are suitable for that purpose. The solubilizing surfactant used is preferably a monohydroxy alcohol

37/52 but polyols, such as that containing 2 to 6 carbon atoms and 2 to 6 hydroxy groups (eg 1,3-propanediol, ethylene glycol, glycerol and
1,2-propanediol) can also be used. Such carriers are usually used in a total amount of 5% by weight to 90% by weight, preferably 10% by weight to 50% by weight, based on the total weight of the detergent formulation. Detergent formulations can also be used in the so-called “single liquid dosage” form.
[00145] Also an aspect of the invention is a granule comprising
a) from 1 to 99% by weight, based on the total weight of the granule, of at least one compound of formula (1) as described above and of at least one peroxide,
b) from 1 to 99% by weight, based on the total weight of the granule, of at least one binder,
(c) from 0 to 20% by weight, based on the total weight of the granule, of at least one encapsulating material,
d) from 0 to 20% by weight, based on the total granule weight, of at least one additional additive, and
e) 0 to 20% by weight based on the total weight of the granule, water. [00146] The granules according to the invention comprise a water-soluble organic polymer as a binder. Such polymers can be used simply or in the form of mixtures of two or more polymers. [00147] The water-soluble polymers that they take into account are, for example, polyethylene glycols, copolymers of ethylene oxide with propylene oxide, gelatin, polyacrylates, polymethacrylates, polyvinylpyrrolidones, vinylpyrrolidones, vinyl acetates, polyvinylpyridine, polyvinylimidazole oxides, vinylpyrrolidone copolymers with long-chain olefins, vinylpyrrolidone copolymers with vinylimidazole, poly (vinylpyrrolidone / dimethylaminoethyl methacrylates), copolymers of
