Abstract

12,126. Farbenfabriken vorm. F. Bayer & Co. May 21, 1910, [Convention date]. Samples furnished. Trisazo dyes are obtained by combining a diazosulphonic or diazo carboxylic acid with an amine of the benzene series having a free para-position, rediazotizing, combining the diazoazo compound with a second molecule of the same or a different amine of the benzene series having a free para-position, diazotizing again, and combining with nitro-m-phenylenediamine, nitro-m-toluylenediamine, or 1:3-dioxyquinoline; one of the middle components above-mentioned may be replaced by 1-naphthylamine or its 6- or 7-sulphonic acids; when one of the middle components contains a sulphonic group, a non-sulphonated amine such as aniline may be used as first component. The following combinations are specified : -2-naphthylamine-3:6- disulphonic acid, m-toluidine, m-toluidine, and nitro-m-phenylenediamine; 2-naphthylamine-4: 8-disulphonic acid, alpha-naphthylamine, cresidine, and nitro-m-phenylenediamine; aniline, 1-naphthylamine-7-sulphonic acid, m-toluidine, and nitro - m - phenylenediamine ; aminoazobenzene sulphonic acid, p-xylidine, and nitro-m-phenylenediamine. Other sulphonic or carboxylic acids of the benzene or naphthalene series may be used as first components; aniline, o- or manisidine or their homologues or substitution products may be used as middle components; when aniline is used as middle component, the formaldehyde bisulphite compound or .toluenesulphoanilide is preferably used. The products dye cotton orange to reddish-blue to brown shades. The products with dioxyquinoline as end component have similar properties. Specifications 3673/00, 7292/00, 3654/03, and 5484/08 are referred to.
