PROCEDURE

实验过程

The nitroanthraquinone used was composed of 69.1% of 1-nitroanthraquinone, 0.7% of 2-nitroanthraquinone and 26.8% of dinitroanthraquinone, and the 1-aminoanthraquinone content in the effluent aminoanthraquinone dry cake was 73.6%. The reduction yield from 1-nitroanthraquinone to 1-aminoanthraquinone was 99.7%. The crystals of the aminoanthraquinones obtained in this and following Examples 2-6 are represented by FIG. 2. They had excellent filterability as tested by a rotary vacuum filter or a pressure filter and could be efficiently separated from waste water of reduction.
