Abstract

26,508. Bloxam, A. G., [Akt.-Ges. f³r Anilin-Fabrikation]. Nov. 22. Dyes, artificial.-Disazo dye-stuffs are obtained by diazotizing and combining with a naphthol, a naphthol sulphonic acid, an aminonaphthol sulphonic acid, or the like, a monoazo dye-stuff of the type where R= a naphthol sulphonic or a dioxynaphthaene sulphonic acid, or according to the Provisional Specification, aminonaphthol sulphonic or naphthylamine sulphonic acid. In an example, the preparation is described of the disazo dye from #-naphthol, and the diazo compound of the dye from picramic acid and 2 :6-naphthol sulphonic acid described in Specification No. 26,416, A.D. 1906. In this example, #-naphthol may be replaced by 2: 6-naphtholsulphonicacid or 1: 8-aminonaphthol-4- sulpbonic acid ; in place of the mono-azo dye-stuff specified above, those obtained from picramic acid and 1 4-naphtbol sulphonic acid, 1 : 5-naphtholsulphonic acid, or 1 : 8-dioxynaphthalene-3:6- disulphonic acid, may be employed.
