摘要
概括了1,1′-二羟基-5,5′-联四唑二羟胺盐(TKX-50)化合物的合成与制备、晶体特性和力学性能,总结了其在性能改进、相容性、能量、安全性等应用方面的研究现状。对比了TKX-50与传统中性有机硝铵类材料的不同,指出TKX-50是离子盐结构,无传统含能基团—NO_(2),释能方式是以高能键断裂释放能量而不是氧化还原反应,使得计算得到的生成焓、爆热、燃烧热等能量特性与试验结果有巨大差异;最后归纳总结了TKX-50的应用优势和存在问题,并展望了其未来发展方向及研究重点,指出应充分挖掘以TKX-50为代表的富氮类含能离子盐能量特性,利用此类材料特有性质,扩大其在火炸药领域应用范围。
The synthesis and preparation,crystal properties and mechanical properties of dihydroxylammonium-5,5′-bistetrazole-1,1′-diolate(TKX-50)compound are introduced,and the current research status on performance improvement,compatibility,energy,and safety applications are summarized.The difference between TKX-50 and traditional neutral nitramine explosives were compared.The TKX-50 is an ionic salt structure without the traditional energetic group—NO_(2),and the energy release method is by breaking high-energy bonds instead of redox reactions,which brings the calculated energy characteristics such as enthalpy of formation,detonation heat,and combustion heat have a large difference with the test results.Finally,the application advantages and existing problems of TKX-50 were summarized,and the future development direction and research focus were prospected.It is pointed out that the energy characteristics of nitrogen-rich energetic ionic salts represented by TKX-50 should be fully exploited,and the special properties of such materials should be utilized to expand their application in the field of propellants and explosives.
