    1-Methyl-3,5-diamino-1,2,4-triazole(DAMT)was synthesized by condensation and cyclization of methyl hydrazine dihydrochloride with cyanoguanidine in ethanol and water. The key influence factor of cyclization was studied. The result showed that the optimum conditions are as follows:Hydrochloric acid is as acid component,the mixed solvent of water and ethanol as reaction medium,the ratio of dicyandiamide and methyl hydrazine(mol)is 1: 1. 1 ~ 1: 1. 2,the reaction temperature is 50 ℃,and pH = 9 ~ 10.
