Procedure

A mixture of 79.1 g of 1,8-diaminonaphthalene, 57.4 g of 96% strength sulphuric acid and 700 ml of water is initially introduced into the reaction vessel at 50° C., and 57.8 g of hydroxy acetone are metered in over a period of 10 minutes. The mixture is then subsequently stirred at 50° C. for 2 hours and cooled to 0° C., and the product is isolated by filtration and dried at 70° C. in vacuo.
