Abstract

1405222 4-Amino-2-nitro-diphenylamine BRISTOL-MYERS CO 29 Oct 1973 [30 Oct 1972] 50234/73 Heading C4P [Also in Division C2] A process for preparing 2-nitro-4-aminophenyl-aniline- (4-amino-2-nitro-diphenylamine) comprises reacting 4-fluoro-3-nitroaniline with aniline at at least 140‹ C. in the presence of a large molar excess of aniline, the molar ratio of aniline to 4-fluoro-3-nitro-aniline being at least 5 : 1. The compound is useful as a red hair dye, and is employed as a component in the blending of hair dye compositions which give naturallooking shades on living hair. [GB1405222A]
