Abstract
312,678. Rintelman, W. L., and Goodrich, R. J. Jan., 31, 1928. o : o<1>-Dicarboxydiphenyldiaminoanthraquinones are prepared by heating a dihalogenanthraquinone under pressure with anthranilic acid, its salts or derivatives, in the presence of an alcohol boiling below 100‹ C. and copper or a copper salt as catalyst. In an example, 1 : 5-dichloranthraquinone is heated with potassium anthranilate in the presence of methyl alcohol and basic copper acetate. the o :o<1>-dicarboxydiphenyl-1 : 5-diaminoanthraquinone being obtained. Ethyl and isopropyl alcohols are also mentioned as examples of alcohols that may be used in the process.
