Abstract

406. Imray, O., [Farbwerke vorm. Meister, Lucius, & Br³ning]. Jan. 9. Dyes, artificial.-Leuco compounds of dyes are prepared by heating with sulphuric acid mixtures of alkylated diamidobenzhydrols or the corresponding methane derivatives with p-oxy-, or pamido-diphenylamines or their derivatives. The use of the following bodies is described, namely, p-oxydiphenylamine, r-amidodiphenylamine, pamidodiphenylmethylamine, C6H5N(CH3)C6H4NH2, p-amidophenyltolylamine, p-diamidodiphenylamine, dimethyl-p-amido-p-oxyphenyltotylamine, tetramethyl- or tetra-ethyl-diamidobenzhydrol, or the corresponding methane derivatives.
