Procedure

Crude 1-nitroanthraquinone (composition of organic substances: anthraquinone, 0.5 wt.%; 1-nitroanthraquinone, 82 wt.%; 2-nitroanthraquinone, 5 wt.%; 1,5-dinitroanthraquinone, 0.5 wt.%; other dinitroanthraquinones and others, 12 wt.%) was reacted with ammonia, and the reaction mass obtained was filtered to obtain crude 1-aminoanthraquinone wet cake.
