国外四嗪四唑类高氮含能材料研究进展

Progress in High-nitrogen Energetic Materials Derived from Tetrazine and Tetrazole

对国外正在研究的四嗪、四唑类高氮含能材料进行了综述,介绍了部分四嗪、四唑类高氮化合物及其衍生物的合成、理化性质和应用前景,对国外研究的3,6 二肼基 1,2,4,5 四嗪(DHT)、3,3′ 偶氮(6 氨基 1,2,4,5 四嗪)(DAAT)、3,6 双(1氢 1,2,3,4 四唑 5 氨基) 1,2,4,5 四嗪(BTATz)、联四唑(BHT)等进行了重点描述。

The research developments of high-nitrogen energetic materials are reviewed. The synthesis and properties of some new compounds derivated from tetrazole and tetrazine,especially 3,6-dihydrazino-1,2,4,5-tetrazine(DHT),3,3′-azobis(6-amino-1,2,4,5-tetrazine)(DAAT),3,6-bis (1H-1,2,3,4-tetrazol-5-yl-amino) -1,2,4,5-tetrazine(BTATz) and 5,5′-bitetrazole(BHT) are discussed. Because of their much more positive heats of formation and higher density,these high-nitrogen compounds are unique in their gas generating ability with a little or without smoke and produced residue. They may have a great future for applications in insensitive explosives,low signature propellants,gas generants and low-smoke pyrotechnics.
