Abstract
Sulphonated carbazoles are made by treating with sulphonating agents at 0-60 DEG C. anthraquinone compounds of the formula <FORM:0650928/IV (c)/1> where X is hydrogen, halogen, alkyl, or alkoxy, and Y is hydrogen, alkyl, halogen, or acylamino. The products dye wool, leather, super-polyamides, and natural silk brown-yellow to brown shades. Sulphonating agents are concentrated sulphuric acid, the monohydrate, oleum, and chlorsulphonic acid, or mixtures thereof. The 1-acylamino groups may be acetylamino, chloracetylamino, propionylamino, phenylacetylamino, hexahydrobenzoylamino, benzoylamino, halogenbenzoylamino, nitrobenzoylamino, amino- or methoxy-benzoylamino, and phthaloylamino. The starting materials are prepared by condensing a 1.5-aminohalogenanthraquinone with an aminodiphenyl followed by acylation, or from a 1-acylamino - 5 - halogenanthraquinone and an aminodiphenyl, followed by acylation, if necessary. Examples describe the treatment with sulphonating agents of 1-benzoylamino-5-(41-phenylamilino)-anthraquinone and of 1-benzoylamino - 5 - benzoylbenzidino - anthraquinone. A further list of starting materials variously substituted as indicated is also given.
