disodium 6-amino-4-hydroxy-5-[(4-nitro-2-sulphonatophenyl)azo]naphthalene-2-sulphonate Usage And Synthesis
UsesAcid Violet 1 (CAS# 6441-91-4) is an organic azo dye used with linen fabrics.
Preparation2-Amino-5-nitrobenzenesulfonic acid?diazo, and 6-Amino-4-hydroxynaphthalene-2-sulfonic acid?in acid conditions coupled.
Properties and Applicationspurple. Purple powder, soluble in water (red light purple), ethanol (red light purple) and soluble fiber element, slightly soluble in acetone and benzene insoluble in other organic solvents. Meet strong sulfuric acid is orange brown, after dilute for purple; Meet nitric acid solution for red turn brown. Its water solution and strong hydrochloric acid for purplish red color, add thick sodium hydroxide solution to blue. Used for wool, wool fiber blended fabric dyeing and printing, white sex good, can also be used in leather and paper color.
