Reaction Steps

Example 1 of DE-A-31 27 193 was reworked: in a 250 ml glass reactor, 59.9 g of 50% strength aqueous cyclohexylamine and 0.1 mol of 2-mercaptobenzothiazole were heated to 85° C. with vigorous stirring, with the resulting cyclohexylamine salt of 2-mercaptobenzothiazole going largely into solution. After the mixture had been cooled to 45° C., 92 g of 5% strength hydrogen peroxide (0.135 mol) were metered in over the course of 60 min with vigorous stirring. Stirring was continued for 30 min at the same temperature, and then the reaction mixture was cooled to room temperature, and the precipitate was filtered off, washed with 10% strength cyclohexylamine solution and water, and dried. Cyclohexylbenzothiazolylsulphenamide was obtained in a yield of 75.6% of theory (melting point 99°-100° C.; purity (Lichty titration) 97.6%).
