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.
