Benzenesulfonic acid, 2,2'-(1,2-ethenediyl)bis[5-nitro-, reaction products with 3-[(4-aminophenyl)azo]benzenesulfonic acid monosodium salt Usage And Synthesis
Preparation
in reflux conditions, sodium hydroxide solution in (E)-2-(2-sulfo-4-nitrostyryl)-5-nitrobenzenesulfonic acid?with 3-Aminobenzenesulfonic acid sodium diazo with aniline?coupled with heating products.
Properties and Applications
yellow orange. Soluble in water for orange. The strong sulfuric acid for purple, yellow as diluted. The dye solution to join hydrochloric acid color becomes dark; Add sodium hydroxide have orange precipitation. Used for cellulose fiber dyeing, leather and paper color. 80 ℃ dyeing, the largest of the cellulose fibre affinity, good levelness.
