| Preparation | 4-(4-Aminophenyl)benzenamine double nitriding, first coupled with 2-Hydroxybenzoic acid, and then and 3-Amino-5-hydroxynaphthalene-2,7-disulfonic acid?diazo, in acid conditions and 4-Methylbenzene-1,3-diamine coupled to a product matches, then hydrolysis benzene sulfonic acid ester base, its products as coupling components again with diazo of 4-Aminonaphthalene-1-sulfonic acid?matches. | | Properties and Applications | red light brown. Soluble in water for yellow brown, and adequate soluble in ethanol and soluble fiber element, insoluble in other organic solvents. The strong sulfuric acid for blue-ray purple or brown and violet black, yellow to red light brown after diluted precipitation; In the nitric acid for brown; In 10% of sodium hydroxide solution for blue-ray red. The dye solution to join strong hydrochloric acid for red orange brown; Add thick sodium hydroxide solution have orange brown precipitation.
