Preparation

Naphthalen-2-ol amine 8 diazo, and 3,5-Dimethylbenzenamine?coupling, again diazo, and 5-Amino-7-ehtoxy-2-naphthalenesulfonic acid coupling, its product to diazo, and 4-Acetamido-5-hydroxynaphthalene-2,7-disulfonic acid coupling (finally coupling is with the sodium bicarbonate water cut in Pyridine in).

Properties and Applications

green. Soluble in water for the green, soluble in ethanol. For the strong sulfuric acid, diluted is green. The dye solution to join strong hydrochloric acid have pale-green precipitation; Add thick sodium hydroxide solution for the green.
