Versuchsvorschrift

1-Nitroanthraquinone (96.4%, 3.4%-dinitroanthraquinones), (7.6 g; 0.03 mole), dimethylformamide (50 ml), and sodium formate (4.1 g; 0.06 mole) were stirred at 130° C. for 17 hours. There was a slow evolution of gas during the reaction period. The reaction mass was cooled, mixed with water (300 ml) and acidified with 32% hydrochloric acid. The resulting suspension was stirred for one hour and filtered. The cake obtained was washed with water, then dried to give 1-hydroxyanthraquinone (6.6 g; 0.03 mole) which by gas chromatographic analysis contained 96.4% 1-hydroxyanthraquinone; 1.8% 1-nitroanthraquinone and 1.8% anthraquinone.
