1-AMinoanthraquinone cas no 82-45-1
1. Nitration of anthraquinone by acid nitro nitro anthraquinone, the reaction product is filtered and washed with hot water to neutral, with sodium sulfite refining. The 2-nitroanthraquinone and sodium sulfite to produce water soluble in anthraquinone-2-sulfonate, filtered and washed away. The obtained 1-nitroanthraquinone is reduced with sodium sulfide to obtain the crude 1-aminoanthraquinone, and the diamine anthraquinone is purified by adding the alkali solution and the insurance powder to purify it, and then oxidizing, filtering and drying to obtain the finished product .
