FIELD: organic chemistry, chemical technology. SUBSTANCE: invention describes method of synthesis of 1-acetyl-3,5-diamino-1,2,4-triazole. Method involves heating dicyanodiamide and hydrazine dihydrochloride in water at 45-50 C, treated with sodium hydroxide for 15-20 min followed by acetylation with acetic anhydride at stirring and at mole ratio dicyanodiamide : : hydrazine salt : NaOH : (Ac)2O = 1:1:2:(1-1.5). EFFECT: decreased cost of end product, retained level of quality.
