Abstract
PURPOSE: To obtain the title compound useful as dye intermediates readily and safely in high quality and purity, by partially oxidizing 1-nitroanthraquinone containing dinitro derivatives hydrogenated under specific conditions.
CONSTITUTION: 1-Nitroanthraquinone containing dinitro anthraquinones or 1- amino-anthraquinone containing diaminoanthraquinones is hydrogenated in the presence of a catalyst, e.g. Pd supported on a carrier, and a base in water or its mixture with an organic solvent at 10W80°C to give 1-amino-and diaminoanthrahydroquinone. After removing the catalyst, 1-amino-anthraquinone is added to the reaction mixture to oxidize soluble diaminoanthrahydroquinones partially into insoluble diaminoanthraquinones, which are eliminated. The reaction mixture is oxidized with an oxidizing agent to give the title compound.
