disodium 3-[[4-[[4-amino-6(or 7)-sulphonatonaphthyl]azo]phenyl]azo]-6-[(2,4-diaminophenyl)azo]-4-hydroxynaphthalene-2-sulphonate Chemical Properties,Usage,Production

Preparation

4-Nitrobenzenamine diazo, and 5-Aminonaphthalene-2-sulfonic acid and 8-Aminonaphthalene-2-sulfonic acid matches, will the nitro reduction for amino, product to diazo, and 6-Amino-4-hydroxynaphthalene-2-sulfonic acid?coupling, generation of accidentally nitrogen compounds to diazo, and Benzene-1,3-diamine coupling (31560). Note: the above structure is in (FIAT 764) about Columbia Black FF examples given in this, but the real structure have not been determined. 4-Nitrobenzenamine diazo, and 5-Aminonaphthalene-2-sulfonic acid and 8-Aminonaphthalene-2-sulfonic acid matches, will the nitro reduction for amino, product to diazo, in alkaline conditions and 6-Amino-4-hydroxynaphthalene-2-sulfonic acid?coupling, generation of accidentally nitrogen compounds to diazo, and 4-Methylbenzene-1,3-diamine coupling (C i.. 31565)

Properties and Applications

black. Black uniform powder. Soluble in water for red light black, soluble in soluble fiber element, slightly soluble in alcohol, insoluble in other organic solvents. In the dark for the strong sulfuric acid to navy, diluted dark red light for blue or black; In nitric acid solution for red; In strong hydrochloric acid slightly soluble in, red to grey. The dye solution to join strong micro red sodium hydroxide solution. Mainly used for cotton, hemp, such as glue of cellulose fiber dyeing, also suitable for silk, polyamide fiber dyeing. Especially suitable for wool/stick blended fabric dyeing a bath.
