摘要通过用取代的5-氨基四唑处理亚硝酸钠和盐酸,高收率合成了一系列1,3-双(2-烷基四唑-5-基)三氮烯。使用红外光谱,1 H NMR和13 C NMR光谱以及高分辨率质谱仪(HRMS)对所有化合物进行了全面表征。这些三氮烯大多数具有良好的爆炸性能,可与TNT媲美,熔点低至81°C至106°C,适用于熔铸炸药。在这些化合物中,1,3-双(2-叠氮基乙基四唑-5-基)三氮烯(2g)的熔点低(106°C),起始分解温度适中(183°C),爆炸性能好(D:7087) m / s; P:17.6 GPa)。
differentiation of the two isomers of disubstituted tetrazoles are rarely studied, which is very important information for designing advanced materials based on tetrazoles. In this article, pairs of 2,5- and 1,5-disubstituted tetrazoles were carefully designed and prepared for study on their thermal decomposition behavior. Also, the substitution fashion of 2,5- and 1,5- and the substituents at C-5 position
The N5-linear energetic moiety of pentazadiene, a new high-nitrogen linkage in energetic materials, has been constructed for the first time from a triazene precursor.
