disodium hydrogen bis[5-[(5-chloro-2-hydroxyphenyl)azo]-6-hydroxynaphthalene-2-sulphonato(3-)]chromate(3-) Chemical Properties,Usage,Production

Preparation

5-Chloro-2-methoxybenzenamine diazo, and 6-Hydroxynaphthalene-2-sulfonic acid coupling, and then in water solution and formic acid chromium heating, in 125 ~ 135 ℃ keep 7 hours, make its formed chromium complex, in chrome complexation processes medium armor oxygen radicals displacement into hydroxyl.

Properties and Applications

blue purple. Purple, brown powder, insoluble in water, soluble in ethanol, slightly soluble in soluble fiber element. The strong sulfuric acid dyes for blue-ray red, diluted into purple; In 10% of sodium hydroxide solution for blue-ray red. The water solution is purple, and 10% sulfuric acid to blue. Levelness and discharge of copper ions in dyeing color becomes the blue, encounter iron ion very dark colored. Used for wool, silk, polyamide fiber and wool blended fabric dyeing and printing directly, also used in leather color. The product are used for worsted, coarse woolen clothes, The female comb.
