Abstract

Acid wool dyes are obtained by causing primary or secondary amines to react upon 1 - amino - 4 - halogen - 2 - sulphoanthraquinone - 6 - or 7 - sulphonamides, in which the sulphonamide group may be substituted by alkyl, aryl or hydroaryl groups. According to examples 1 - amino - 4 - bromo - 6 - (dimethyl) sulphonamide - anthraquinone - 2 - sulphonic acid is condensed with hexahydroaniline and p-aminoacetanilide; the corresponding 6-sulphodiethylamide is condensed with methylamine and the corresponding 7-sulphomethylamide is condensed with aniline. The products are greenish-blue dyes. Specification 399,095 is referred to. The amino-anthraquinone sulphonamides are obtained by heating a 1 - nitro - 6 - or 7 - sulphoanthraquinone with phosphorus pentachloride, treating the sulphochloride obtained with ammonia or an amine, and reducing the nitro group to amino.
