Versuchsvorschrift

17.5 liters (STP)/hour of ammonia are passed, under normal pressure, for 40 minutes into a solution of 60 g of 1,5-dinitro-anthraquinone (97% pure) and 5 g of ammonium bromide in 450 g of diethylene glycol, at 220° C, while stirring vigorously. After cooling, the product is filtered off and washed with water. After drying, 46.5 g of 80.5% pure 1-amino-5-nitroanthraquinone (71.5% of theory) are obtained. The product contains 19.0% (19.0% of theory) of 1,5-diaminoanthraquinone.
