Abstract

Vat dyestuffs of the triazoloanthraquinone series, of the general formula <FORM:0468686/IV/1> where R is a cyclic radicle having up to two isocyclic non-hydrogenated rings and A is a radicle capable of being vatted which may be attached to R by an atomic bridge, and in which the anthraquinone nucleus shown may contain any substituents, are manufactured by coupling the diazo compound of an amine NH2--R--A with a 2-aminoanthracene and oxidizing the resulting o-aminoazo compound, or, when A is a second triazoloanthraquinone radicle, by coupling 1 molecular proportion of a tetrazonium salt with 2 molecular proportions of a 2-aminoanthracene and oxidizing the resulting disazo compound. The oxidation may be effected in a single operation, or in two stages with intermediate production of a triazoloanthracene. In examples: (1) tetrazotized 4 : 4<1>-diaminodiphenyl is coupled with 2-aminoanthracene and the product is oxidized with chromium trioxide in the presence of nitrobenzene and glacial acetic acid; the product dyes vegetable fibres yellow shades from a hot vat; (2) 4 : 4<1>-diaminodiphenylurea is tetrazotized and coupled with 2-aminoanthracene, and the product is oxidized as in (1); the product dyes cotton reddish yellow-brown shades; the tetrazo component may be replaced by 4 : 4<1>-diaminodiphenyl ketone, the product dyeing cotton brown shades from a black-green vat; (3) anthraquinone-2-carboxylic acid chloride is condensed with p-nitraniline, the nitro group is reduced by means of sodium sulphide solution, the amine is diazotized and coupled with 2-aminoanthracene, and the product is oxidized as in (1); the product dyes cotton yellow shades from a violet vat. Samples have been furnished under Sect. 2 (5) of dyestuffs prepared as follows: (A) anthraquinone - 1(N) : 2 : 2<1>(N) : 1<1> - acridone - 5<1> - carboxylic acid chloride is condensed with p-nitraniline and the product is reduced, diazotized, coupled and oxidized as in (3) above; the product dyes cotton from a violet vat orange shades; (B) anthraquinone-2(S) : 1 : 1<1>(S) : 2<1>-thioxanthone-6<1>-carboxylic acid chloride is similarly reacted; the product dyes cotton from a violet vat yellow shades.
