    摘要:

    发展具有高能、低感、高热稳定性的新型含能材料是人们一直追求的目标。本研究设计、合成了一系列基于四唑连4,8-双呋咱并[3,4-b,e]吡嗪(DFP)的含能离子盐。含能离子盐具有优异的综合性能,如热分解温度较高(Td:> 260 ℃),感度较低(IS≥ 20 J,FS≥360 N)和爆速较高等(D > 8800 m·s-1)。值得特别指出的是,化合物4e的热分解温度高达314 ℃,并且其爆速及撞击感度分别为9005 m·s-1和25 J,是一种极具潜力的钝感高能量密度材料。

    Abstract:

    The development of new energetic materials with high energy, low sensitivity, and high thermal stability is always desirable. In this study, a series of tetrazole-linked 4, 8-dihydrodifurazano [3, 4-b, e] pyrazine (DFP) based energetic salts have been synthesized and fully characterized. The as-synthesized energetic salts exhibited excellent comprehensive performances in terms of high decomposition temperature (Td > 260 ℃), low mechanical sensitivity (IS≥20 J and FS≥360 N), and high detonation velocity (D > 8800 m·s-1). Notably, the thermal decomposition temperature of di (aminoguanidinium)-4, 8-di (1H-tetrazol-5-yl)-difurazano [3, 4-b, e] pyrazine (compound 4e) is up to 314 ℃, while its detonation velocity and impact sensitivity are highly desirable with the values of 9005 m·s-1 and 25 J, respectively. Overall, these novel energetic compounds have shown their great-potential as insensitive high-energy-density materials.
