disodium 4-amino-3-[(4-aminophenyl)azo]-6-[[4-[[4-amino-6(or 7)-sulphonatonaphthyl]azo]phenyl]azo]-5-hydroxynaphthalene-1-sulphonate Usage And Synthesis
Preparation4-Nitrobenzenamine diazo, and 5-Aminonaphthalene-2-sulfonic acid and 8-Aminonaphthalene-2-sulfonic acid matches, will the nitro reduction for amino, again diazo, and 4-Nitrobenzenamine diazo, in acid conditions and 4-Amino-5-hydroxynaphthalene-1-sulfonic acid coupled to product matches, then will the nitro reduction.
Properties and Applicationsgreen and black. Soluble in water, slightly soluble in soluble fiber element, insoluble in other organic solvents. The strong sulfuric acid for blue to blue-ray black, diluted for purple, have precipitation; In the light of nitric acid solution for dark brown. The dye solution for blue-ray black, add thick sodium hydroxide solution to blue.
