摘要:The invention relates to a process for the preparation of 1,4-diamino-2,3-dicyanoanthraquinone, starting from 1,4-diaminoanthraquinones, or salts thereof, of the formula ##STR1## wherein n is 0, 1 or 2. To introduce the two cyanide radicals, the starting material is treated, in the presence of an oxidizing agent, with a compound which donates cyanide ions. The process comprises using as solvent a mixture of a carboxamide, an N-alkylated carboxamide or a lactam and water, which mixture contains more than 10% by weight of water. n 1,4-Diamino-2,3-dicyanoanthraquinone is an important intermediate for the synthesis of textile dyes.
