Abstract

Bactericidal azo dyestuffs are manufactured by coupling diazotized arylamines or their substitution products with 3 : 5-diaminopyridine or its homologues or substitution products, e.g. its halogen, hydroxy, alkoxy or alkyl derivatives. In examples, aniline is diazotized and coupled with: (1) 3 : 5-diaminopyridine; (2) 2 - hydroxy - 3 : 5 - diaminopyridine (obtained by reduction of 2-hydroxy-3 : 5-dinitropyridine). Samples have been furnished under Sect. 2 (5) of the following dyestuffs: (A) p-chloraniline --> 3 : 5-diaminopyridine; (B) p-anisidine --> 3 : 5-diaminopyridine; (C) b -naphthylamine --> 3 : 5-diaminopyridine; (D) sulphanilic acid --> 3 : 5-diaminopyridine; (E) anthranilic acid --> 3 : 5-diaminopyridine. Specification 341,598 is referred to.
