Preparation

3,3′-Dimethoxylbenzidine double nitriding, and ??8-Hydroxynaphthalene-1,6-disulfonic acid and 4-Hydroxy-7-(phenylamino)naphthalene-2-sulfonic acid, and then put three pulpous state dye and copper sulfate sodium acetate and water mixing 1.5 days and nights form a tight mixture, again in the 120 ~ 125 ℃ conditions vacuum drying. In this process, the two?methoxy groups are replaced by hydroxyl groups.

Properties and Applications

blue. Soluble in water for red light blue, soluble in ethanol. The strong sulfuric acid for green light blue, diluted for dark purple. The dye solution to join strong hydrochloric acid for purple, have precipitation; Add thick sodium hydroxide solution have red light blue precipitation.
