反应详情

A mixture of 301 g of 1,7-dinitroanthraquinone (99%) and 1 liter of ethyleneglycol dimethylether was reacted with 510 g of ammonia in an autoclave over a period of 4 hours at a temperature of 130° C. (molar ratio 30 : 1; pressure 60 atms). After cooling, the reaction mixture was poured into 5 litres of water and the deposit which precipitated was filtered off under suction, washed with water and dried. Yield: 264 g of a 93% 1-amino-7-nitroanthraquinone (91% of the theoretical yield).
