    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.1,4-Diamino-2,3-dicyanoanthraquinone is an important intermediate for the synthesis of textile dyes.

    摘要： The invention relates to a process for the preparation of 1,4-diaminoanthraquinone-2-sulfonic acid by sulfonating 1,4-diaminoanthraquinone or leuco-1,4-diaminoanthraquinone, which comprises carrying out the sulfonation at elevated temperature with oleum as sulfonating agent, with or without the addition of a Lewis base. The 1,4-diaminoanthraquinone-2-sulfonic acid is used in particular for synthesizing anthraquinoid disperse dyes for dyeing hydrophobic fibre materials.

    摘要： The compounds of the formula ##STR1## in which the substituents and indices are as defined in claim 1, are green direct dyes for various substrates, in particular cellulosic fibre materials. They are stable to high temperatures and are therefore particularly suitable for the one-bath, one-stage dyeing of polyester/cotton mixed fabrics together with a disperse dye for the polyester fibres, under the dyeing conditions for polyester fibres.
