摘要

本研究有效合成了噻唑-4-甲酰肼（SZCA）及其离子盐 SZCA-HClO4，以及高能络合物 Cu(SZCA)2(ClO4)2（ECC-1）。通过元素分析、红外光谱、13C NMR 光谱和热稳定性分析，对新化合物 SZCA、SZCA-HClO4 和 ECC-1 进行了全面表征。氧弹量热法测量了 ECC-1 的燃烧热，并分别用 Kamlet-Jacobs 公式和 EXPLO5 预测了其引爆性能。采用 BAM 法测试了 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爆实验全面评估了 ECC-1 的起爆能力。结果表明，ECC-1 的分解温度为 236 ℃，具有可接受的机械灵敏度（冲击灵敏度：3.4 J，摩擦灵敏度：4 N）和良好的起爆性能（D：6.6 km s-1，P：21.3 GPa）。单脉冲激光（λ：808 nm，P：20 W，t：3 ms）可触发 ECC-1，并成功引爆下一个装药，如 RDX 和 CL-20。

A new sulfur-containing laser-sensitive primary explosive based on thiazole-4-carbohydrazide

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.
