FIELD: organic chemistry, chemical technology.
SUBSTANCE: invention relates to a method for synthesis of 1,2,4-triazolone-3- representing the parent component used in the creature of energy-saturated materials - gun powders, fuels, explosive substances, blowing agents. Method involves interaction of acetone semicarbazone with formic acid in the presence of 96% sulfuric acid as the reaction activating agent in the mole ratio of reagents = 1:(4.5-5.5):(0.35-0.45), respectively, at temperature 107-110°C for 12 h. Method provides simplifying the process and to enhance the yield of the end product.
EFFECT: improved method of synthesis.
