Procedure

140 g of sulfuric acid are added dropwise in the course of half an hour to a liquid mixture of N-benzoyl-caprolactam (21.7 g, 100 mmol) and water (8.0 g, 440 mmol) at 68° C. The internal temperature increases in the course of this to 80° C., and the mixture is further stirred for 1 hour at this temperature. After the reaction solution is cooled to 20° C., 42 ml of 50% strength aqueous hydrogen peroxide solution are added dropwise. The internal temperature is kept between 25° and 30° C. during this by ice cooling. After one hour, the reaction batch is admixed with 500 ml of ice water, and the resulting colorless precipitate is filtered off by suction and washed to neutrality with water. Yield 22.2 g (88%), active oxygen content 6.2 % (98%).
