Versuchsvorschrift

100 g of a dinitroanthraquinone mixture of the composition A are employed and are stirred with C ml of nitrobenzene at D° C. for B hours, the precipitate is filtered off at D° C. and washed with 50 ml of nitrobenzene and the material on the filter is freed from nitrobenzene in vacuo. E g of 1,7-dinitro-anthraquinone of the composition F are obtained.
