Abstract

519,437. Dyestuff intermediates ; dyeing. KERSHAW, A., SAUNDERS, K. H., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Sept. 22, 1938, No. 27669. [Classes 2 (iii) and 15 (ii)] New arylamides for producing insoluble azo dyes on the fibre are made by interacting aminoarylpyridines with o-hydroxyaryl carboxylic acids, e.g., 2:3-hydroxynaphthoic acid, 6 - bromo - and 6 - methoxy - 2:3 - hydroxynaphthoic acids, 2:3-hydroxycarbazole carboxylic acid, 2:3-hydroxydiphenylene oxide carboxylic acid and 2:3-hydroxyanthracene carboxylic acid. In examples, (1) the mixture of isomeric 4-aminophehylpyridiries made by reacting pyridine with diazotised p-nitraniline and reducing (Specification 518,886) is reacted with 2:3-hydroxynaphthoic acid or 2-hydroxycarbazole-3-carboxylic acid in presence of phosphorus trichloride, (2) the mixture of isomeric 4 - amino - 3 - methylphenylpyridines made by diazotizing 1-amino-4-acetamino-3- methylbenzene, reacting with pyridine, and de-acetylating the product is reacted with 2:3-hydroxynaphthoic acid ; (3) the mixture of isomeric 4-aminophenyl-alpha-picolines made by reacting diazotized p-nitraniline with alpha-picoline and reducing is reacted with 2:3-hydroxynaphthoic acid, (4) the mixture of isomeric 2 - nitro - 4 - aminophenylpyridines made by nitrating the mixture of 4-aminopyridines made by the process of Specification 518,886, is reacted with 2:3-hydroxynaphthoic acid (5) the mixture of 2-methoxyaminophenylpyridines made by reacting pyridine with diazotized o-anisidine, nitrating, and reducing is reacted with 2:3-hydroxynaphthoic acid, and (6) 2:5-dichloraminophenylpyridine, made by reacting diazotized 2:5-dichloraniline with pyridine, nitrating, and reducing is reacted with 2:3-hydroxynaphthoic acid. In a further example, cotton is impregnated with the arylamide ' mixture obtained according to example (1) and immersed in a bath containing diazotized 5-nitro-2-aminoanisole ; bluish-red dyeings are obtained. The shades produced by developing with diazo compounds of ochloraniline, m-chloraniline, 4-chlor-2-aminoanisole, 5-chlor-2-aminotoluene, 2:5-dichloraniline, 4-benzoylamino-2:5-diethoxyaniline and 4-nitro-2-aminoanisole are tabulated.
