Abstract
12,828. Bloxam, A. G., [Akt.-Ges. f³r Anilin-Fabrikation]. May 26. Monobenzyl- and benzylidene-aminoanthraquinones and derivatives thereof are obtained by the action of a benzyl halide or a benzal halide or benzaldehyde or a substitution derivative thereof, on an aminoanthraquinone or a substitution derivative thereof, such as a brom or chlor derivative but not aminoanthraquinone sulphonic acids, amino derivatives of a-aminoanthraquinone, or derivatives without a free ortho position to the benzylamino or benzylideneamino group ; benzylaminooxyanthraquinones are also excluded. The following products are specified :-benzyl-2-aminoanthraquinone, benzylidene-2-aminoanthraquinone, monobenzylidene-2 : 6- or -2 : 7-diaminoanthraquinone, dibenzylidene - 2 : 6-diaminoanthraquinone, p - di - methylbenzylidene-2-aminoanthraquinone. Sulphuretted dyes.-Vat dyes are obtained by heating the above described products with sulphur ; the dyes probably contain a thiazole ring. The production of the dyes may be effected without isolating the intermediate benzyl or benzylidene compounds. Dyes are specified from benzylidene- 2-aminoanthraquinone, p-dimethylaminobenzylidene-2-aminoanthraquinone, dibenzylidene-2 :6- diaminoanthraquinone, and monobenzylidene-2: 6- diaminoanthraquinone. The last-mentioned product, after dyeing on cotton in the vat, can be diazotized on the fibre and developed with #-naphthol.
