    1458827 Chromium complex azo dyes containing bidentate chelates PRODUITS CHIMIQUES UGINE KUHLMANN 19 Dec 1973 [28 Dec 1972] 58743/73 Heading C4P Novel chromium complex dyestuffs which do not contain SO 3 H or silver halide developing substituents have the formula wherein nucleus A optionally contains up to 3 non-ionic substituents; B is the residue of a benzene, naphthalene, acetoacetanilide or heterocyclic coupling component which may contain up to 3 non-ionic substituents; Y<SP>1</SP> 1 is O or CO.O ; y<SP>1</SP> 2 is fixed on B in the ortho position with respect to the azo linkage and is O or NH; D is the residue of a bidentate chelating agent; and Z is a molecule of ammonia or an organic base. They are prepared by treating a metallizable monoazo compound of the formula wherein Y 1 is OH, OCH 3 or CO 2 H and Y 2 is OH or NH 2 and is ortho to the azo linkage with a salt of trivalent chromium at 110-130‹ C. in a polar solvent of b.pt. > 110‹ C. and then reacting the 1 : 1 cationic chromium complex thus obtained with a bidentate chelating agent in the presence of ammonia or an organic base. Suitable chelating agents include #-diketones, ohydroxy - aldehydes, o - nitroso - phenols and -naphthols, peri - hydroxy - quinones and N- heterocycles containing OH peri to N. Suitable bases include pyridine, laurylamine, ethylamine and ethanolamine. The novel dyestuffs may be used to dye or print fibres based on polyamides, polyesters or cellulose triacetate and for the coloration of bulk macromolecular synthetic materials such as polyesters and polyamides.

    (54) METHOD OF OBTAINING CHROMO COMPLEX NITROGEN
    U - 4 tons of oxygen or .. COO group; - an oxygen atom or an —NH group; X is CH- or -N-; D - residue of a biocompound chelating agent selected from the group: -diketone, o-hydroxyaldehyde, o-nitrseophenol, o-nitrosoneLtol, perioxychinonon;
    2 - ammonia or pyridine molecule.
    The method consists in the interaction of azo or azomethine derivative with hexahydrate chromium chloride at 115 125 ° C in glycol or diethylene glycol medium followed by the interaction of the resulting 1: 1 cationic chromo complex with a bidentate chelating agent in the presence of ammonia or pyridine.
    In the examples below, parts are weight.
    Example. 30.9 h of nitro-4-hydroxy-2-benzene monoazo dye} - | 1-azo-11-1oxy-2 naphthalene | heat up to 1,200 ° C in 300 parts of diethylene glycol from 21.5 parts of hexahydrate chromium chloride (C fjCr 6H2.0) until the complete 1: 1 chromo complex is obtained. The mixture is cooled to -60 ° C, 12 hours, acetylacetone and 18 hours, 25% ammonia is added. The mixture is then poured onto 2000 parts of cold water, the crystallizing dye is filtered off, washed and dried. His analysis corresponds to the formula
    H5 (
    The same dye is obtained if diethylene glycol is replaced by glycol or any other solvent having a boiling point above 110 ° C.
    If ammonia is 10 parts of pyridine, a dye is obtained having the above formula, in which ammonia is replaced by pyridine.
    In both cases, the resulting dyes have a certain solubility in hydrocarbon solutions, bodies, such as benzene, chlorobenzene, methylene chloride, chloroform, perchlorethylene: chromium-containing complexes 1: 1 or 1: 2 are insoluble in these solvents.
    Example 2 The dye of Example 1 is ground in a paste and crushed for 10 hours of the condensation product cresol-formaldehyde naphtho-sulfonic acid, then dried.
    To 0.15 parts of the dye thus obtained, finely divided, add 100 parts of water and 0.5 parts of o-dichlorobenzene. 5 hours of polyester yarn is placed in this bath, heated for 1 hour before and kept for 1 hour at this temperature. After washing with water and removing excess dye for 15 minutes in a bath containing 1 ml / l of sodium hydroxide, 30%, and a sufficient amount of sodium hydrosulfite to remove loose dye, get a gray-blue shade with good resistance to light and sublimation . Example 3. 0,15 h. The dye of Example 1 in a dispersed state is taken in suspension in 100 parts of water with the addition of 0.5 parts of 10% acetic acid.
    0 acid. When added 5 hours.
    polyamide yarn, heated to LWG. for half an hour and kept for 1 hour at boiling. Get a blue-gray tint of good strength to all
    5 conditions m.Q
    Analogous {& 3 method in examples 4-36 is obtained with various metal complex dyes yarn, the edema of which is shown in Table. one.
    Example 37. 32.3h. dye nitro-5-hydroxy-2-benzene3 | 1-azo-2-1 hydroxy-1-methyl-4-naphthalene is heated to 120-125 seconds in 300 parts of diethylene glycol from 21.5 hours.
    - hexahydrate chloride
    chromium until complete conversion into a 1: 1 chromium complex. Cool the mixture to standby C, add 19.4 parts of benzylacetone, then 10 parts of pyridine. The mixture is drained for 2000 hours of cold water, and
    0 The crystallizing dye is filtered, washed, dispersed and dried. The resulting dye of the formula
    colors polyester fibers black.
    Substitutions in this example, beyloacetone other chelating agents, get on polyester fibers shades listed in table. 2
    PRI me R 46. 12.2 parts of salicylaldehyde are affected by 18.85 parts of chlorine 6-6-nitro-4 amino-2-phenol in 150 parts of diethylene glycol. Then 27 hours of hexahydrate are added.
    chromium chloride, and heat the mixture to 115c for 5 hours. The solution is cooled until cooled and 10 hours of acetylacetone and 31.6 parts of pyridine are added. The terature is maintained for 3 hours, then the drainage solution in SOO including cold water. Chris лиз llizuition with the dye is filtered out of the mouth and dried, it paints the polyester fibers yellow.
    PRI me R 47. Mixes 1 hour. the dye of example 1 with 50 hours of polyester in the form of granules or powder, then the mixture is heated to 280-300 ° C and yarns are formed. The threads are cooled, then drained. They are painted in neutral black.
    Apply 0.25 parts of the dye of Example 1, yarns are obtained in gray.
    In both cases, the color is excellent light fastness.
    Example 48. Polyamide granules are dyed according to example 3 with the dye from example 15. Colored granules melt at a temperature of 250,280 s and turn into a thread or an orange colored product with good light fastness.
    The mixture of polyamide granules and the dye from Example 16 can also be melted and turned into orange threads or articles with horoid resistance to light.
    The proposed method makes it possible to obtain dyes with an increased affinity for polyester fiber, good dyeing and lightfastness.
