Abstract

1503204 Preparation of aminonitrodihydroxyanthraquinones BASF AG 15 May 1975 [12 June 1974] 20557/75 Heading C4P Compounds of formula where one X is OH and the other X is NO 2 are prepared by reducing a dinitrodihydroxyanthraquinone with substantially the stoichiometric amount of hydrazine in a phenol as solvent at a temperature from 40‹ C. to the boiling point of the reaction mixture. The amount of phenol used is preferably 2À5 to 20 times the weight of the dinitrodihydroxyanthraquinone.
