Abstract

333,188. Chemische Fabrik vorm. Sandoz. Nov. 27, 1928, [Convention date]. Anthraquinone dyes. - Water-soluble anthraquinone dyestuffs are prepared by treating a derivative of the general formula where X represents hydrogen, methyl or ethvl and AC represents acyl, with a sulphate, phenol and water under pressure to 130‹-140‹ C. Complete substitution of bromine by a sulpho group occurs without any splitting off of the acyl group. In examples 1-ammo-2-bromo-4-p-aminoacetanilideanthraquinone, and 1 amino-2-bromo-4-paminomethylacetanilidoanthraquinone are converted to the corresponding 2-sulphonic acid derivatives. The prior art is referred to. The Specification as open to inspection under Sect. 91 (3) (a) also refers to the treatment of derivatives of the above general formula wherein X further represents benzyl, but this subjectmatter does not appear in the Specification as accepted.
