Preparation

4-(4-Aminophenyl)benzenamine double nitriding, first?coupled with 2-Hydroxybenzoic acid, and then in acid conditions and 4-Amino-5-hydroxynaphthalene-1-sulfonic acid coupling, 2-(4-Aminophenylamino)-2-oxoacetic acid diazo,?In alkaline conditions and the resulting azo compound coupling group then hydrolyzed oxamate.

Properties and Applications

Dark olive green. Moderate soluble in water for olive. The strong sulfuric acid in purple, blue and black light for orange, for olive diluted. The dye solution to join strong hydrochloric acid have red light olive brown precipitation; Add thick sodium hydroxide solution for palm light olive, and have precipitation.
