Abstract

2 - Diphenyl - benzthiazole - 6 - carboxylic acid chloride of the formula: <FORM:0761687/IV(b)/1> is produced by condensing 3-mercapto-4-aminobenzoic acid hydrochloride with diphenyl-4-carboxylic acid chloride in pyridine.ALSO:The invention comprises dyes of the formula:-<FORM:0761687/IV(b)/1> (where R is hydrogen, alkyl, aryl, or a heterocyclic radical), and a method of making them by condensing a corresponding benzthiazole - 6 - carboxylic acid chloride with 6 - amino - 31, 41 - phthaloyl - acridone. The products dye vegetable fibres blue shades. In examples, 6 - amino - 31, 41 - phthaloyl - acridone is condensed in dichlorbenzene with benzthiazole - 6 - carboxylic acid chloride and its 2 -phenyl 2 - methyl, 2 - (p - xenyl) (see Group IV(b)) and 2-furyl derivatives. Specification 417,980 [Group IV] is referred to.
