Abstract

Pure 1-nitroanthraquinone (I) is prepd. from mixtures of nitroanthraquinones by treatment of (40-250 degrees C pref. 70-150 degrees C) in organic solvents (N,N-dimethylformamide) contg. is not >10 wt.% water in presence of 0.1-10 wt.% of an inducer liberating nitrite, chloride, bromide etc., by bases (alkali carbonates, amines e.g. trimethylamine) or cpds. contg. >=1 -CH2-group activated by carbonyl, (diethylketone). Amt. of base or carbonyl cpd. is 0.3-3 moles/mole dinitroanthraquinone in the mixt. (I) is an inter for dye mfr.
