Abstract

Process for the separation of aminoanthraquinones, characterized in that the composition formed by several types of aminoanthraquinones, preferably 1-aminoanthraquinone, 2-aminoanthraquinone and diaminoanthraquinone is subjected to a dissociative extraction treatment by distribution in a two-phase liquid system consisting of a aqueous phase, acid, and an organic phase not miscible with water, whose phases are separated from each other and the selected amine is isolated therein.
