Among energetic materials, there is a significant challenge faced by researchers to seek an optimal balance between high performance and safety. By combination of furoxan and 1,2,4-oxadiazole backbones and C–NO2 moieties, a promising energetic molecule, bis(4-nitro-1,2,5-oxadiazole-2-oxid-3-yl)-azo-1,2,4-oxadiazole (6), was prepared and characterized by IR, multinuclear NMR spectroscopy, elemental
在高能材料中,研究人员面临着巨大的挑战,要在高性能和安全性之间寻求最佳平衡。通过呋喃喃和1,2,4-恶二唑骨架和C–NO 2部分的组合,一个有前途的高能分子,双(4-硝基-1,2,5-恶二唑-2-氧化-3-基)-偶氮-制备了1,2,4-恶二唑(6),并通过IR,多核NMR光谱,元素分析,DSC测量和单晶X射线衍射进行了表征。它具有高密度(1.92 g cm -3),可接受的热稳定性(182°C)和高形成热(1188.8 kJ mol -1 /2.8 kJ g -1)。计算的爆震性能(D = 9666 ms -1和P = 42.8 GPa)与CL-20相当(9706 ms -1和45.2 GPa)。更重要的是,它显示出理想的冲击和摩擦敏感度(IS:12 J,FS:180 N),不如HMX(IS:7.4 J,FS:120 N)敏感。此外,进行了化合物6的爆炸试验。结果表明,化合物6比常用的二次炸药RDX更强大(D
