3,5-二硝基-1,2,4-三唑盐的制备

Preparation of 3,5-dinitro-1,2,4-triazole salt

以双氰胺与二盐酸肼为原料,经缩合环化、重氮化、硝化得到3,5-二硝基-1,2,4-三唑(DNT)的水溶液,通过碳酸氢钠及硝酸银分别得到DNT的钠盐及银盐,得率分别为67.2%、33.6%。精制后,钠盐m.p.139～141℃,银盐m.p.235～238℃并通过红外光谱(IR)对其结构进行了表征。

3,5-Dinitro-1,2,4-triazole（DNT） was synthesized from hydrazine dihydrochloride and cyanoguanidine by condensation,cyclization,diazotization and nitrification.Sodium salt and silver salt of DNT were synthesized from silver nitrate and sodium bicarbonate.The total yield was 67.2% and 33.6%,and the melting point（m.p.） were 139～141℃ and 235～238℃.The structure of purity prepare compound was characterized by IR.
