disodium 7,7'-iminobis[3-[(2,4-dimethylphenyl)azo]-4-hydroxynaphthalene-2-sulphonate] Chemical Properties,Uses,Production
Preparation
2,4-Dimethylbenzenamine (2 Moore) diazo, and Bis(4-hydroxy-2-sulfonaphthalene-7-yl)amine coupling (2,4-Dimethylbenzenamine can part with heterogeneous, or other aromatic amine replace).
Properties and Applications
red light purple. Soluble in water for red light purple, slightly soluble in ethanol (for pink) and soluble fiber element. The strong sulfuric acid to red light purple, diluted for darkness product red; In nitric acid for colourful orange, then turn dark colored. The dye solution to join strong hydrochloric acid for red light purple; Add sodium hydroxide solution have strong purplish red precipitate.
