Reaction Steps
A mixture of 298 g of 1,7-dinitro-anthraquinone (99%) and 3 liters of propionitrile is reacted with 510 g of ammonia (molar ratio 30 : 1, pressure 60 atmospheres) in an autoclave at 140°C for 4 hours. 260 g of a 97% 1-amino-7-nitro-anthraquinone (95% of the theoretical yield) are obtained after working-up as described in Example 12.
