Abstract
1428620 Preparing aminoanthraquinones BAYER AG 21 March 1974 [22 March 1973 14 June 1973] 12584/74 Heading C4P 1-Amino, 1,5-diamino- and 1,8-diaminoanthraquinones, and mixtures thereof, are prepared by reacting at elevated temperature and pressure the corresponding nitroanthraquinone with ammonia in an ether, an aliphatic or cycloaliphatic hydrocarbon or an optionally alkyl-substituted aromatic hydrocarbon or a mixture thereof. The reaction preferably takes place at 100-220‹ C. using a molar ratio of ammonia to 1-nitroanthraquinone of at least 2 : 1, e.g. 10 : 1 to 40 : 1, or of ammonia to 1,5- and/or 1,8-dinitroanthraquinone of at least 4 : 1, e.g. 10 : 1 to 80 : 1. The pressure is preferably not less than 20 atmospheres. The process may be used to prepare pure 1- aminoanthraquinone from mixtures of 1- and 2-nitroanthraquinones, the latter remaining unreacted.
