实验步骤: 63.3 g of 1-nitroanthraquinone (99% pure) in 320 ml of cyclohexane are reacted with 147.8 g of isopropylamine (molar ratio 10:1) for 70 minutes at a temperature of 160° C. and under a pressure of 50 bars. Working up analogously to Example 1 gives 62 g (94.5% of theory) of 97.6% pure 1-isopropylamino-anthraquinone.

实验步骤: 384 g of isopropylamine and 1,390 g of o-xylene are initially introduced into a stainless steel autoclave, which has a capacity of 5 l and is fitted with a stirrer and steam jacket heating, and are heated to 165° C. A suspension of 543 g of 1-nitroanthraquinone with a purity of 98.4% by weight in 815 g of o-xylene is injected into the autoclave in the course of 20 minutes (molar ratio 3:1). During the addition the pressure rises from 10 to 40 bars and the temperature rises from 165 to 170° C. The reaction has ended after a further 30 minutes at 170° C. After cooling and letting-down, the residual solution is evaporated. 548 g of 1-isopropylaminoanthraquinone with a purity of more than 98% are obtained. is fitted with a stirrer steam jacket heating is injected into the autoclave in the course of 20 minutes (molar ratio 3:1) During the addition the pressure rises from 165 to 170° C After cooling the residual solution is evaporated

实验步骤: The use of polar solvents as reaction media results in only very poor yields and lengthy reaction times are required. For example, the reaction of 1-nitroanthraquinone with a 300% excess of isopropylamine at 75° C after 100 hours gives a yield of only 70% of 1-isopropylaminoanthraquinone. The use of polar solvents as reaction media results in only very poor yields lengthy reaction times at 75° C after 100 hours
