disodium 3-[[4-[[4-[(2,4-diamino-5-nitrophenyl)azo]-m-tolyl]azo]-o-tolyl]azo]naphthalene-1,5-disulphonate Usage And Synthesis
Preparation
3-Aminonaphthalene-1,5-disulfonic acid diazo, and m-Toluidine coupling, again diazo, and O-Methylaniline coupling, its product to diazo, and 4-Nitrobenzene-1,3-diamine coupling.
Properties and Applications
orange brown. Soluble in water for yellow brown, soluble in soluble fiber element for orange, soluble in ethanol, insoluble in other organic solvents. The strong sulfuric acid for blue to red sauce, diluted becomes shallow, with brown precipitation; In nitric acid partly dissolved for blue purple. The dye solution to join strong hydrochloric acid with brown precipitation; Add thick sodium hydroxide solution for orange brown.
