trisodium 3-[[1-hydroxy-6-[[[[5-hydroxy-6-(phenylazo)-7-sulphonato-2-naphthyl]amino]carbonyl]amino]-3-sulphonato-2-naphthyl]azo]benzoate Chemical Properties,Uses,Production
Preparation
aniline diazo, coupled with N,N’-bis(4-hydroxy-2-sulfonaphthalene-7-yl)urea, 3-Aminobenzoic acid diazo, and the generation of single accidentally coupled nitrogen compounds.
Properties and Applications
red light orange to yellow light was red. Red brown powder. Soluble in water for red orange to brown, 80 ℃ in the solubility of 10 g/L, slightly soluble in ethanol for gold orange. The strong sulfuric acid in red for product, after diluted to orange, red orange precipitation. The dye solution to join strong sodium hydroxide solution for orange brown; Add 10% sodium hydroxide solution slightly darker; With strong hydrochloric acid have red precipitate; Add 10% sulfuric acid had not changed. Hard to more sensitive. Used for cellulose fiber, silk, wool, polyamide fiber dyeing, fiber fabric printing, also can be used for leather color. Good Exhaust dyeing.
