112.1 g (0.5 mole) of 2-hydroxyanthraquinone are dissolved in 500 ml of N-methylpyrrolidone, and 12 g (0.5 mole) of sodium hydride are added in portions. When the evolution of gas has ended, 46.37 ml (0.5 mole) of epichlorohydrin are added dropwise at 70° C. and stirring is continued at 70° C. for a further 8 hours. 1.5 liters of water are then added, the mixture is filtered and the filter cake is dried in vacuo. After drying, the product is boiled up again in 1 liter of N,N-dimethylformamide with 10 g of active charcoal and filtered hot. The crystals which precipitate on cooling to 0° C. are separated off by filtration and dried under a high vacuum. 69.45 g (50.57% of theory) of 2-anthraquinonyl glycidyl ether are obtained;
