Abstract
1476519 Dinitroanthraquinones BAYER AG 12 Sept 1974 [14 Sept 1973] 39795/74 Heading C2C Dinitroanthraquinones are produced by nitrating an anthraquinone in the presence of an indifferent organic solvent, an indifferent solvent being one which undergoes little or no reaction with the nitrating agent under the reaction conditions. Preferred indifferent organic solvents are aliphatic or alicyclic hydrocarbons having up to 12 carbon atoms and substituted once or several times by halogen atoms or nitro groups.
