The synthesis of 3-(1,2,4-oxadiazolyl)-5-nitratomethyl isoxazole (C6H4N4O5), its physical properties, and its theoretical performances are described. This energetic material was found to have a melting point range of 76.6–79.2 °C, and a thermal onset decomposition temperature of 184.5 °C. These thermal features put this material into the standalone melt-castable explosive class. The material was found
3-(1,2,4-恶二唑基)-5-硝基甲基异恶唑(C 6 H 4 N 4 O 5 )的合成),描述了它的物理性质和理论性能。发现这种含能材料的熔点范围为 76.6–79.2 °C,热起始分解温度为 184.5 °C。这些热特性使这种材料成为独立的可熔铸炸药类别。发现该材料具有 TNT 性能,尽管具有硝酸酯官能团,但对冲击、摩擦和静电放电不敏感。制造该分子的关键反应是二氨基乙二肟的去对称化。描述了这种转换的优化。以前关于这种去对称化的报告被发现是不准确的,因为去对称化反应产生了单和双 1,2,4-恶二唑产物的共晶。
