Manufacturing Methods :  (a) 1,5-Dihydroxy-4,8-dinitro-9,10-dioxo-9,10-dihydroanthracene-2,6-disulfonic acid reduction, and then will be generated 1,5-dihydroxy 4,8-Diamino anthraquinone-2-sulfonic acid Leuco oxidation, and translated into sodium salt; (b) 1,5-Diamino-4,8-dihydroxyanthracene-9,10-dione with low concentration hair smoke sulfuric acid in 120 ~ 130 ℃ sulphonated; (C) 1,5-Dihydroxy-4,8-dinitro-9,10-dioxo-9,10-dihydroanthracene-2,6-disulfonic acid with sodium sulfide; (d) 1,5-Dimethoxy-4,8-dinitroanthraquinone and sodium sulfite deoxidization reaction, then use 70% sulfuric acid hydrolysis; (e)1,5-Diamino-4,8-dihydroxyanthracene-9,10-dione in the presence of boric acid with hair smoke sulfuric acid were single; (f) will C.I. Acid Blue 45 (C.I. 63010) with the reducing agent part, take off the acid.

Properties and Applications: blue. Blue powder. Slightly soluble in ethanol and soluble fiber element, insoluble in acetone, benzene, carbon tetrachloride, pottery, especially solvent. Strong sulfuric acid in a yellow olive green, diluted into purple. Mainly used for dyeing wool carpet, also used in wool, silk, polyamide fiber fabric dyeing, can also be used in leather dyeing.
