What is trisodium 7-[[4-[[4-[[6-[(4-aminobenzoyl)amino]-1-hydroxy-3-sulphonato-2-naphthyl]azo]benzoyl]amino]-o-tolyl]azo]naphthalene-1,3-disulphonate ?

Preparation

7-Aminonaphthalene-1,3-disulfonic acid diazo, and a coupling m-Toluidine?condensation, and then will the nitro reductive into amino, its product to diazo, and 7-(4-Aminobenzamido)-4-hydroxynaphthalene-2-sulfonic acid coupling.

Properties and Applications

red light orange. Soluble in water for orange brown, slightly soluble in ethanol is palm light orange. The strong sulfuric acid for blue-ray in red, for orange brown after diluted. The dye solution to join strong hydrochloric acid have dark brown precipitation; Add thick nitrogen oxidation sodium solution have orange brown precipitation. Used for cellulose fiber dyeing, Exhaust dyeing and levelness are good.
