Versuchsvorschrift

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.
