Abstract

26,478. Johnson, J. Y., [Badische Anilin & Soda Fabrik]. Dec. 7. Dyes, artificial.-Monoazo dyes are obtained by combining with #-naphthol the diazo compounds of 4-chlor-5-methyl-2-nitraniline, 4-methyl-5-chlor-2- nitraniline, or 4 : 5-dichlor-2-nitraniline. The products yield lakes insoluble in oil. The coupling is preferably carried out in presence of excess of acetate, and Turkey-red oil, oleic acid, soap, or a substratum such as heavy spar, may be present. 4-Chlor-5-methyl-2-nitraniline is obtained by nitrating 2-chlor-5-acettoluidine and saponifying the resulting nitro-compound ; 4.chlor-5-methyl- 6.nitraniline may be formed simultaneously.
