Abstract
Benzoic acid-4-sulphopiperidide is obtained by reacting the sulphochloride with piperidine in water.ALSO:Vat dyestuffs of the formula <FORM:0635924/IV (c)/1> are made by the process of the parent Specification using an anthraquinone derivative having a halogen atom in one of the b -positions of ring II. The products dye or print wool, silk, cotton, linen, artificial silk, regenerated cellulose, and nylon. In examples, benzene-1-carboxylic acid-4-(N-dimethyl)-sulphonamide is reacted with (1) a mixture 1-amino-4-benzoylamino-6- and 7-chloranthraquinones; (2) the 7-chloro body only; (3) 1-(p-bromo benzoylamino) - 4 - amino - 6 - chloroanthraquinone; (4) a mixture of 1-(p-chlorobenzoylamino)-4-amino-6-and 7-chloranthraquinones; (5) 1-(p-methoxybenzoylamino) - 4 - amino - 6 - chloranthraquinone or a mixture of the 6- and 7-chlor bodies; (6) 1.4- diamino-6-chloranthraquinone. Also in examples: (7) benzoyl chloride is reacted with a mixture of 1-amino-4-[Bz.4-(M - dimethyl) - sulphonamido - benzoylamino] - 6- and 7-chloranthraquinones or with the 7-chlor body only; (8) benzoic acid-4-sulphopiperidide is reacted with a mixture of 1-amino-4-benzoylamino-6- and 7-chloranthraquinones or the 7-chlor body only. Other acyl groups specified are: 4-phenyl-sulphone benzoyl, 4-iodobenzoyl, 3.4.5-trimethoxybenzoyl, 4-fluorobenzoyl, 4-phenoxybenzoyl, 4-cyanobenzoyl, 3-methoxybenzoyl, cinnamyl, naphthoyl; other sulphonamide groups specified are: sulphodiethylamide, sulphodiallylamide, sulphodibenzylamide, sulphopiperidide, sulphomorpholide, sulphomethylphenylamide. A list is given of various combinations of 6- and 7-chloro substituents in ring II with various of the sulphonamide and acyl groups specified in the above list and in the examples. The 1 - acylamino - 4 - amino - 6 - and 7 - chloroanthraquinones referred to above are obtained from the corresponding 1-amino-4-nitro-chloranthraquinones by appropriate acylation, followed by reduction with phenylhydrazine. Benzoic acid-4-sulphopiperidide is obtained by reacting the sulphochloride with piperidine in water.
