Uses and synthesis of 1,4-Diamino anthraquinone powder

1,4-Diamino anthraquinone powder Dark purple needle crystals (in pyridine) or purple crystals. Soluble in benzene, pyridine, nitrobenzene, aniline, slightly soluble in hot acetic acid, ethanol. 1,4-Diamino anthraquinone CAS 128-95-0 is widely used for reducing grey BG, dispersive turquoisant blue HBF and acid dyes. 1,4-Diamino anthraquinone Raw Materials were synthesized by condensation of hydroquinone and anhydride to produce 1, 4-dihydroxy-anthraquinone, and then aminated to produce 1, 4-diaminoanthraquinone leuchromosome, and then oxidized with fuming sulfuric acid.
