Production methods:

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 .

2. Anthraquinone sulfonic acid Salt salicylic acid anthraquinone and fuming sulfuric acid in the presence of mercuric sulfate to produce anthraquinone-1-sulfonic acid, neutralized by ammonia, and then replaced with sodium salt, and then in the m-nitrobenzene sulfonate catalyzed ammonia hydrolysis 1-amino anthraquinone, refined after the finished product.
