ACID BLUE 25 Usage And Synthesis
UsesAcid Blue 25, is used for dyeing wool, silk and mixed fabric and printing them in a direct method.Dyes and metabolites.
Preparation(a) 1-Amino-2,4-dibromoanthracene-9,10-dione?with aniline condensation, its product 1-amino-4- anilino-2-bromo-anthraquinone?in phenol in pressure with aqueous sodium sulfite, were hot. (b) the 1-Amino-4-bromo-9,10-dioxo-9,10-dihydroanthracene-2-sulfonic acid (sodium) in water medium copper salt as the catalyst used with aniline condensation.
Flammability and ExplosibilityNonflammable
Properties and Applicationsblue. Blue powder. The little blue soluble in water, but soluble in acetone, ethanol, slightly soluble in benzene, four hydrogen naphthalene, insoluble in nitrobenzene and xylene. Meet strong sulfuric acid as dark, after diluted blue precipitation. Mainly used for dyeing nylon, polyamide for supporting the dye. Can also be used for wool, silk and blended fabric dyeing and printing directly. Can also be used in leather, electrical-controlled aluminum soap and color.
