The method of obtaining 4-amino-1,2,4-triazole by reacting hydrazine with formic acid in the presence of an inorganic phosphorus-containing compound, characterized in that, in order to simplify, intensify the process and increase the yield of the target product, an alkaline phosphate is used as the inorganic phosphorus-containing compound metal in an amount of 0.01-1 mol per 1 mol of hydrazine, and the process is carried out at 100-140 C. 2. The method according to claim 1, characterized in that the alkali metal phosphate is used in an amount of 0.01-0, 2 mol per 1 mol hydra ins. 3. A method for producing 4-amino-1,2, 4-triazole by reacting hydrazine and an inorganic formic acid derivative in the presence of phosphoric acid, characterized in that, in order to simplify, intensify the process and increase the yield of the target product, as an inorganic formic derivative acids use an alkali metal formate, the ratio of hydrazine, alkali metal formate and phosphoric acid being 1.0: 1.0: g (1.0-1, and, the process is carried out at 100-140 ° C. 4. Method pop. 3, different Yuschi and so 5 oshchenilas hydrazo sha, alkali metal formate and phosphoric acid is 1.0: 1.0: 1.0 to about C O E9. |
