C.I. Acid Blue 45 (by (a) 1,5-Dihydroxyanthracene-9,10-dione sulfonation, again nitrifying generated disulfonic Acid, then use Sodium sulfide reduction; (b) using Sodium bisulfite treatment 2,4,6,8-Tetrabromo-1,5-dihydroxyanthracene-9,10-dione or 1,5-Dihydroxy-2,6-dichloro-4,8-dinitroanthraquinone; (C) in the presence of copper with ammonia treatment 2,4,6,8-Tetrabromo-1,5-dihydroxyanthracene-9,10-dione?or?1,5-Dihydroxy-2,6-dichloro-4,8-dinitroanthraquinone?with hydrochloric Acid acidification. | [Synthesis]
4,8-Diamino-1,5-dihydroxyanthraquinone-
2,6-disulfonic acid is prepared from 1,5-dihydroxyanthraquinone
by sulfonation, nitration, and
reduction . | [Properties and Applications]
blue. Blue powder. In alkaline aqueous solution in have greater solubility. Light resistance, heat resisting fastness are high. Mainly used in high-grade adornment coloring. |
