FIELD: organic chemistry, chemical technology. SUBSTANCE: synthesis of 3,5-dinitro-1,2,4-triazole salts is carried out by interaction of alkaline metal carbonates or hydrocarbonates with 3,5-dinitro-1,2,4-triazole solution in acetone. To synthesize 3,5-dinitro-1,2,4- triazole hydrazine hydrate, hydrochloric acid and dicyanodiamide are heated in the mole ratio 1:2:1 and temperature 45-50 C and formed solution is poured to sodium nitrite an aqueous solution at 40-50 C at vigorous stirring. Invention can be used in production of biologically active compounds and nitro-derivatives of 1,2,4-triazole used in different fields. EFFECT: decreased cost of process, enhanced safety of process. 2 tbl, 4 ex
