What is tetrasodium 2-[[4-[[4-[[1-hydroxy-6-(phenylamino)-3-sulphonato-2-naphthyl]azo]-7-sulphonato-1-naphthyl]azo]-1-naphthyl]azo]benzene-1,4-disulphonate ?

Preparation

2-Aminobenzene-1,4-disulfonic acid diazo, and Naphthalen-1-amine coupling, its product to diazo, and 5-Aminonaphthalene-2-sulfonic acid coupling, again diazo, in alkaline conditions and 4-Hydroxy-7-(phenylamino)naphthalene-2-sulfonic acid coupling.

Properties and Applications

blue. Blue gray powder. Soluble in water as dark blue, solubility of 50 g/L (60 ℃), 60 g/L (97 ℃), soluble in alcohol. The strong sulfuric acid for blu-ray black, diluted for dark purple. The dye solution to join strong hydrochloric acid generation navy to purple precipitation; Add sodium hydroxide solution for red light purple, have precipitation. Cellulose fiber of dyeing, temperature in 80 ℃ maximum when affinity. Good levelness, discharge sex very good: dyeing encounter copper, iron ion basic discoloration. Mainly used for silk, cotton viscose things and carpet of dyeing and printing. But with disperse dyestuffs dye polyester/stick blended fabric. Suitable for a bath dyeing of step. Can also be used for paper dyeing and manufacturing color pigment sediment
