Abstract

103,479. Oman, E. Jan. 14, 1916, [Convention date]. Samples furnished. Azo dyes are obtained by coupling aromatic diazo compounds with lignine sulphonic acid or its salts, prepared from waste sulphite-cellulose lye. The products are light-red to dark-brown in colour; they precipitate from the solution or are separated by addition of a salt. According to examples, aniline, 2 - naphthylamine - 6 : 8 - disulphonic acid, and benzidine are used as diazo components. Instead of lignine sulphonic acid, waste sulphite-cellulose lye itself may be employed.
