Preparation

3,3′-Dimethoxylbenzidine double nitriding, and 4,5-Dihydroxynaphthalene-2,7-disulfonic acid (2 Moore) coupling, and then will pulpous state dye and copper sulfate and ammonia water solution, form a tight mixture mixing, again in the 120 ~ 125 ℃ conditions vacuum drying. In this process, two methoxy groups are replaced by hydroxyl groups.

Properties and Applications

blue. To black powder. Soluble in water for blue, not soluble in alcohol. The strong sulfuric acid dyes for green light blue, dilute to blue. The dye solution to join strong hydrochloric acid into a red light blue precipitation; Add thick sodium hydroxide solution for blue still, precipitation. Water-soluble is good, is very sensitive to that fights. Dyeing copper and iron ion in the green color. Discharge sex and levelness is better. Used for cotton, viscose and their blended fabric and silk dyeing, general is not used for printing. Also used in paper color.
