| Hazard Information | Back Directory | [Preparation]
3-Amino-4-hydroxybenzenesulfonic acid diazo, and Resorcinol coupling, in 30 ℃ with water cut copper sulfate processing, get copper complex as coupling components; 7-Aminonaphthalene-1,3-disulfonic acid diazo, and m-Toluidine coupling, again diazo, and m-Toluidine coupling, and then and 4-Nitrobenzoyl chloride?condensation, will the nitro reduction for both the amino nitrogen, and the generation of coupling components coupling. | [Properties and Applications]
yellow light brown. Soluble in water for orange brown, soluble in ethanol. The strong sulfuric acid in red for brown + purple, for yellow brown after diluted. The dye solution to join strong hydrochloric acid for olive brown, have precipitation; Add thick sodium hydroxide solution for orange brown, have precipitation.
