Abstract

368. Newton, P. A., [Farbenfabriken vorm. F. Bayer & Co.]. Jan. 6. Samples furnished. Triphenylmethane dyes.-Dyes of the triphenylmethane series are obtained by condensing formaurine dicarboxylic acid or formaurinedimethyldicarboxylic acid with primary, secondary, or tertiary aromatic amines, and oxidizing the leuco compounds so obtained. The formaurine dicarboxylic acid and formaurinedimethyldicarboxylic acid are obtained by treating methylenedisalicylic acid or methylenedi-o-cresotinic acid with oxidizing-agents. The amines specified are :-diethylaniline, dimethylaniline, ethylbenzylaniline, or their chloro, methyl, sulphonic, or carboxylic derivatives, m-ethoxyphenyl-p-tolylamine, p-tolyl-anaphthylamine, p-xylidine. Suitable oxidizing- agents are nitrosylsulphuric acid, nitric acid, fuming sulphuric acid, nitro compounds, &c. The products dye wool red, violet, or blue shades which become fast on chroming. Specification 14,312/09 is referred to.
