C.I. Acid Blue 68 Usage And Synthesis

Preparation

(a) 1,5-Dimethoxyanthracene-9,10-dione?and 1,8-Dimethoxyanthracene-9,10-dione?mixture dinitration, reduction, ethyl products and chemical. In the process of preparing sulphonated medium armor oxygen radicals hydrolysis, then into sodium salt; (b) in the presence of copper, Ethanamine?and 1,5-Dihydroxy-4,8-dibromoanthraquinon?condensation, and then sulphonated; (C)?1,5-Dihydroxy-9,10-dioxo-9,10-dihydroanthracene-2,6-disulfonic acid?and 1,8-Dihydroxy-9,10-anthraquinone-2,6-disulfonic acid?mixture brominated, and then in the presence of copper and Ethanamine?condensation.
