Abstract

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.
