trisodium 5-[[4'-[[4-[(4-amino-7-sulphonato-1-naphthyl)azo]-6-sulphonato-1-naphthyl]azo][1,1'-biphenyl]-4-yl]azo]salicylate Usage And Synthesis
Preparation
4-(4-Aminophenyl)benzenamine double nitriding, first coupled with 2-Hydroxybenzoic acid, and with 8-Aminonaphthalene-2-sulfonic acid coupling, its product to diazo, and 5-Aminonaphthalene-2-sulfonic acid coupling.
Properties and Applications
dark red light brown. Soluble in water for brown, soluble in ethanol is shallow red sauce. The strong sulfuric acid for blue to blue-black, diluted with light olive green precipitation. The dye solution to join strong hydrochloric acid have olive green precipitation; Add thick sodium hydroxide solution have orange brown precipitation.
