Abstract

9267. Newton, P. A., [Farbenfabriken vorm F. Bayer & Co.]. April 19. Samples furnished. Hexakisazo dyes, which are symmetrical ureas, are obtained by treating sulphonic or carboxylic acids of aminotrisazo compounds of the benzene or naphthalene series, containing one amino group and no free hydroxy group, with phosgene or equivalents thereof such as perchlormethylformate or hexachlordimethylcarbonate. The products dye cotton brown shades. According to an example the trisazo dye from aminoazobenzenedisulphonic acid, mtoluidine, and m-toluidine, is treated with phosgene. The following components are also specified: -4-chloraniline-2-sulphonic acid, o-, p-, or m-sulphanilic acid, aniline, 2-naphthylamine-4:8-disulphonic acid, as first components; m-toluidine, p-xylidine, o-anisidine, cresidine, 1-naphthylamine or its 7-sulphonic acid, as second components; o-anisidine, cresidine, &c. as third components; m-toluidine, p-xylidine, &c. as fourth components.
