Abstract

5183. Akt.-Ges. f³r Anilin-Fabrikation. May 7, 1914, [Convention date]. Monoazo dyes.-A monoazo dye, dyeing wool blue-red shades in acid baths, is obtained by combining diazotized 6-acetylamino-3-amino- 1-methoxybenzene-4-sulphonic acid with 2: 8: 6- aminonaphthol sulphonic acid in acid solution. 6-Acetylamino-3-amino -1- methoxybenzene -4- sulphonic acid is obtained by acidylating 2- aminoanisol-4-sulphonic acid, nitrating, eliminating the acidyl group, reducing the nitro group, and mono-acetylating the resulting diaminoanisol sulphonic acid.
