Reaktionsschritte

Dicyandiamide (84 g) was suspended in 80 ml of water and reacted successively with 97 g sulfaminic acid at 80° C. in such manner that the temperature of 95° C. was not exceeded. The reaction mixture was agitated for another 15 minutes at 95° C. Then the solution was rapidly cooled to 0° C.-5° C., and the resultant colorless crystals were drawn off and washed with 100 ml ethanol. After drying, 181 g (91%) guanylurea sulfamate was obtained.
