Abstract
Guanidine benzenesulphonate has been obtained in yields exceeding 70% by heating urea, ammonium sulphamate, and ammonium benzenesulphonate in respective molar ratios of 1:1:0.75. The effects of temperature, proportion of reactants, and reaction time were studied batchwise. Then the process was operated on a continuous basis in a four-flask cascade reactor at temperatures between 240° and 260 °C.
