    Abstract: A process for the recovery of 1-nitroanthraquinone in a purified state from a nitroanthraquinone mixture containing it by treatment with a base in the presence of an initiator such as nitrite, halide, thiocyanate, alcoholate or phenolate ions in an organic solvent. A 1-nitroanthraquinone is obtained which is essentially pure or contains only small quantities of isomers and dinitroanthraquinones.
