Abstract

PURPOSE: To obtain the titled compound useful as a raw material for synthesizing drugs, pesticides, etc. and for nitration inhibitor in short time in high yields without a side reactin, by adding a specific amount of NH3 to the system of the reaction of dicyandiamide and H2S in a solvent.
CONSTITUTION: In the reaction of dicyandiamide and H2S in a solvent, 2W50g of NH3, preferably 5W20g of NH3 per liter of the solvent is present in the reaction system to give a guanylthiourea. Ethylene glycol or 1,2-propanediol is preferably used as the solvent. The reaction is preferably carried out at 70W110°C at a pressure not more than 10kg/cm2.
