| Abstract: | Sodium citrate was used as a complex catalyst for the titanium trichloride to reduce insoluble azo dyes and pigments in acetonitrile-alcohol-water system. The reducing agents, complexing agents and reducing conditions were studied in detail. A lot of pure samples and commercial samples were determined in order to verify this method. |
