This study effectively synthesized thiazole-4-carbohydrazide (SZCA) and its ionic salt SZCA·HClO4 and energetic complex Cu(SZCA)2(ClO4)2 (ECC-1). The new compound SZCA, SZCA·HClO4 and ECC-1 were fully characterized through elemental analysis, infrared spectroscopy, 13C NMR spectroscopy and thermal stability analysis. The combustion heat of ECC-1 was measured by oxygen bomb calorimetry, and its detonation performance was predicted by Kamlet-Jacobs formula and EXPLO5, respectively. The mechanical sensitivity of ECC-1 was tested using BAM method. In particular, we comprehensively evaluated the initiation ability of ECC-1 through lead plate destruction experiment and laser initiation experiment. The results show that ECC-1 have a decomposition temperature of 236 °C, exhibits acceptable mechanical sensitivity (impact sensitivity: 3.4 J, friction sensitivity: 4 N), and decent detonation properties (D: 6.6 km s−1, P: 21.3 GPa). And ECC-1 could be initiated by a single-pulse laser (λ: 808 nm, P: 20 W, t: 3 ms), and successfully detonated the next charge, such as RDX and CL-20.

一种基于噻唑-4-碳酰肼的新型含硫激光敏感初级炸药


本研究有效合成了噻唑-4-碳酰肼 （SZCA） 及其离子盐 SZCA·HClO 4 和高能配合物 Cu（SZCA）2（ClO4）2 （ECC-1）。新化合物 SZCA、SZCA·通过元素分析、红外光谱、13C NMR 光谱和热稳定性分析对 HClO4 和 ECC-1 进行了充分表征。采用氧弹量热法测定 ECC-1 的燃烧热，分别采用 Kamlet-Jacobs 公式和 EXPLO5 预测其爆轰性能。采用 BAM 方法测试 ECC-1 的机械敏感性。特别是，我们通过铅板破坏实验和激光起始实验综合评价了 ECC-1 的引发能力。结果表明，ECC-1 的分解温度为 236 °C，表现出可接受的机械敏感性（冲击敏感性：3.4 J，摩擦敏感性：4 N）和良好的爆震性能（D：6.6 km s−1，P：21.3 GPa）。ECC-1 可以由单脉冲激光器 （λ： 808 nm， P： 20 W， t： 3 ms） 引发，并成功引爆下一个电荷，如 RDX 和 CL-20。
