Procedure

Sulfaminic acid (97 g) was added batchwise to a solution composed of 84 g dicyandiamide and 300 ml of water at 80° C. whereby the temperature was not permitted to exceed about 95° C. After addition was complete, the temperature was held at 95° C. for 20 minutes, after which the solution was evaporated using a water-jet vacuum. By this process 189 g (=95% of theoretical) guanylurea sulfamate was obtained.
