摘要：
Cyanogen chloride and dimethylamine are reacted in a water/organic solvent system. The organic solvent is immiscible with water. After the completion of reaction, the water-immiscible organic solvent is distilled away from the reaction product solution to carry out the subsequent synthesis of 1,1,3,3-tetramethylguanidine in an aqueous system.
