    摘要: A process for the preparation of 1-amino-8-nitro-4,5-dihydroxyanthraquinone by partially reducing the corresponding dinitrohydroxyanthraquinone and isolating the reduction product, in which crude 1,8-dinitro-4,5-dihydroxyanthraquinone obtained by nitrating 4,5-dihydroxyanthraquinone is partially reduced in a phenol-water mixture, which contains from 5 to 50% by weight of water, in the presence of an alkali metal phenolate, by means of a reductone, reductonate or a mixture of these. The product is virtually free from by-products and is suitable for use for the synthesis of dyes.

    摘要: The production of aminonitrodihydroxyanthraquinones of the formula: ##STR1## in which one X is OH and the other X is NO.sub.2 by partial reduction of the corresponding dinitrodihydroxyanthraquinone or mixtures thereof by heating at 80.degree.-250.degree. C in the presence of 1/2 to 5 times the weight thereof of an unsubstituted or substituted phenol. The reduction is accelerated by being carried out in the presence of a small amount such as 0.5-20 mol percent of an alkaline-reacting agent.
