실험 절차
80 g of a mixed acid containing 33% of HNO3 are added dropwise at 5° to 10° C. in the course of 2 to 4 hours to a solution of 110.0 g of 1,4-dichloroanthraquinone in 600 ml of 96% strength H2SO4. The mixture is allowed slowly to warm to room temperature, and is then stirred for a further few hours, and the precipitated 1,4-dichloro-5-nitroanthraquinone (112.6 g) is filtered off with suction. The mother liquor is stirred into 2 liters of water. The solids are then filtered off with suction, and the press cake is washed with water until neutral and dried at 100° C. 12.7 g of 1,4-dichloro-6-nitroanthraquinone are isolated.
