Procedure

256 g of a 99% 1-nitro-anthraquinone are reacted in 2500 g of 35% aqueous ammonia solution at 190°-200° C for 4 hours in an autoclave. After release of pressure, the reaction product is isolated by removal of the water by distillation under vacuum and dried. Yield: 226 g of a 90% 1-amino-anthraquinone (91% of the theoretical yield) which contains 5 by weight, of 1-amino-anthraquinone imine.
