  作为潜在熔铸炸药的叠氮基和硝基烷基硝基吡唑的合成和表征

  摘要：

  爆炸材料领域令人期待的进步包括开发熔点范围为 80 至 110 °C 的新型可熔铸化合物。由于 TNT（三硝基甲苯）的性能有限且毒性较高，这一点尤为重要。在这项研究中，介绍了一系列创新的熔铸炸药，其特点是在3-硝基-、4-硝基-、3,4-二硝基吡唑或3-叠氮基-4-硝基吡唑支架上连接有硝基烷基和叠氮烷基官能团。这些化合物采用简单的方法合成，并使用各种分析技术进行彻底表征，包括单晶 X 射线衍射、红外光谱、多核核磁共振 (NMR) 光谱、质谱、元素分析和 DTA。此外，还评估并比较了不同结构的化合物的能量特性，例如（理论）性能数据、灵敏度和相容性。
