Discussed herein is the synthesis of bis(1,2,4-oxadiazole)bis(methylene) dinitrate, determination of its crystal structure by X-ray diffractometry, calculations of its explosive performance, and sensitivity measurements. Steps taken to optimize the synthesis process and to improve yields of the dinitrate are also discussed. Bis(1,2,4-oxadiazole)bis(methylene) dinitrate has a calculated detonation pressure 50% higher than that of TNT. The dinitrate compound exhibits a relatively high decomposition temperature that is rarely observed for nitrate-based compounds. The dinitrate was found to have lower sensitivities to impact and friction compared with RDX. It is believed that intramolecular hydrogen bonding observed in the crystal lattice assists in the relatively high thermal stability and relatively low sensitivity of the material.

双(1,2,4-恶二唑)双(亚甲基)精酸盐:高能熔体爆炸性和高能推进剂增塑剂

本文讨论的是双(1,2,4-恶二唑)双(亚甲基)二硝酸酯的合成,通过X射线衍射法测定其晶体结构,计算其炸药性能以及灵敏度测量。还讨论了优化合成过程和提高二硝酸盐收率的步骤。硝酸双(1,2,4-恶二唑)双(亚甲基)酯的计算爆轰压力比TNT高50%。该二硝酸盐化合物表现出相对较高的分解温度,这对于基于硝酸盐的化合物而言很少观察到。与RDX相比,发现该二硝酸盐对冲击和摩擦的敏感性较低。据信在晶格中观察到的分子内氢键有助于材料的相对较高的热稳定性和相对较低的灵敏度。
