disodium 5-[[4'-[(2-amino-8-hydroxy-6-sulphonato-1-naphthyl)azo][1,1'-biphenyl]-4-yl]azo]salicylate Usage And Synthesis
Preparation4-(4-Aminophenyl)benzenamine double nitriding, first with 2-Hydroxybenzoic acid coupling, again in acid conditions and 6-Amino-4-hydroxynaphthalene-2-sulfonic acid?coupling.
Properties and Applicationsblue-ray red. Purple powder. Soluble in water for yellow light red, solubility of 40 g/L (85 ℃), slightly soluble in ethanol, acetone, soluble fiber element, insoluble in other organic solvents. The strong sulfuric acid in blue, diluted to become Red, light Red sauce precipitation; In nitric acid for brown in the red. The dye solution to join strong hydrochloric acid for red light brown, have precipitation appear; Add thick sodium hydroxide solution is for palm orange. Cellulose fiber of dyeing, devoured performance is good, in the 80 ~ 100 ℃ maximum when affinity. This product to sensitive fights. Used for dyeing cotton or viscose, also can be used for direct printing of cotton or viscose to discharge printing color, also used for silk, wool, stick/hair, stick/cotton, leather and pulp dyeing, also can be used in the manufacture of organic pigment sediment color.
