2,4,5-三硝基咪唑有机胺盐的合成与性能

Synthesis and properties of 2,4,5-dinitroimidazole(TNI) salts

以2,4,5-三硝基咪唑(TNI)为原料,合成了TNI的胍盐(GTNI)、三氨基胍盐(TAGTNI)、脒基脲盐(GUTNI)等3种新化合物,并用红外光谱、核磁共振、元素分析等方法鉴定了结构。测试了GTNI、TAGTNI、GUTNI热安定性、密度与燃烧热,计算了生成焓与爆轰参数。结果表明,TAGTNI的生成焓和能量较高。

Three new compounds of TNI, which were GTNI, TAGTNI and GUTNI, were synthesized with 2,4,5-TNI as raw materials. The structure of products were characterized by IR, NMR and elemental anal- ysis, showing that the products were target products. The thermal stability, density and heat of combustion of GTNI, TAGTNI and GUTNI were tested. The enthalpy of formation and detonation parameters of products were calculated. The results showed that energy and the enthalpy of formation of TAGTNI was higher.
