以3,6对(3,5二甲基吡唑)1,2,4,5四嗪(BT)为起始物,经取代反应合成了3,6二氨基1,2,4,5四嗪(DATZ),产率95.3%,再经过氧蚁酸氧化得到四嗪类高氮低感度炸药———3,6二氨基1,2,4,5四嗪1,4二氧化物(DATZO2),产率60.2%;利用IR、NMR、MS、元素分析和DSC等对其结构进行了表征和确认,并对合成反应条件进行了初步探讨,认为最佳反应条件为DATZ1.12g(0.01mol),甲酸20ml,双氧水4ml,25℃反应1h。

3,6-diamino-1,2,4,5-tetrazine （ DATZ ） was synthesized from 3,6-bis （ 3,5-dimethyl-pyrazol-1 oyl ） -1,2,4,5otetrazine （BT） with a yield of 95.3% , DATZ was oxidized with peroxyformic acid to give a high-nitrogen energetic compound 3,6odiamino-1, 2,4,5-tetrazine-l,4-dioxide （DATZO2） with a yield of 60.2%. The structures of both DATZ and DATZO2 are identified and characterized by IR,NMR, DSC, MS,elemental analysis and melting point test etc. Moreover, the effects of reaction conditions on the yield of DATZO2 were studied, and the optimum reaction conditions are DATZ 1. 12 g （0.01 mol）, methane acid 200 ml and hydrogen peroxide 4 ml, reaction time 1 h and reaction temperature 25 ℃.
