sodium [3-[[3-[(3-amino-4-nitrophenyl)azo]-2,4-dihydroxyphenyl]azo]-4-hydroxybenzenesulphonato(3-)]cuprate(1-) Usage And Synthesis
UsesC.I. Acid brown 83 is an acidic brown dye that can be adsorbed and removed by bentone clay.
Preparation3-Amino-4-methoxybenzenesulfonic acid diazotization and coupling resorcinol, then heated in a copper sulfate aqueous ammonia solution, to convert it into a copper complex, and then through diazotization of the 4-Nitrobenzene-1,3-diamine coupling. In the copper complex process methoxy substituted by hydroxyl.
Properties and Applicationsyellow light brown. Soluble in water for yellow brown, not soluble in alcohol. The strong sulfuric acid in red orange for brown, for yellow brown after diluted. In water solution to join strong hydrochloric acid for yellow brown; Add thick sodium hydroxide solution for red orange brown. Apply to wool dyeing, also can be used for leather color.
