摘要： 以碱式碳酸铜和四氮唑乙酸在水中反应制备得到四唑乙酸铜(II)含能配位聚合物, 并培养出单晶. 运用元素分析, FT-IR分析和X-射线单晶衍射对标题配合物的组成和结构进行了全面的表征. 采用差示扫描量热分析(DSC)和热重-微分热重分析(TG-DTG)研究了标题配合物的热分解过程, 表明标题配合物的热分解主要包含三个放热峰. 用Kissinger和Ozawa-Doyle法对标题配合物的第一放热分解过程进行了动力学研究, 计算得到其活化能为356.1 kJ/mol. 对配合物的撞击、摩擦、火焰感度和5s爆发点测试表明该配合物具有一定的感度, 有望作为含能材料应用于相关领域. 同时研究了标题配合物对RDX热分解的影响, 结果表明: 标题配合物可以使RDX的放热分解峰的温度提前16.4 ℃,分解速度加快, 对RDX具有良好的催化作用.

Abstract: Copper based on tetrazole-1-acetate acid (Htza) was synthesized with tetrazole-1-acetate acid and cupric carbonate basic, a new component method in aqueous solution and obtained its single crystal. The molecular formula and structure of the title complex was characterized by using the elemental analysis and FT-IR techniques, which is [Cu(tza)2]n, and the result is in accordance with the X-ray single crystal diffraction data. The thermal decomposition process of [Cu(tza)2]n was investigated by using differential scanning calorimetry (DSC) and thermogravimetry-derivative thermogravimetry (TG-DTG), which indicated the thermal decomposition of the title compound displayed three exothermic decompositions and the first exothermic decomposition kinetic parameters Ea and A of these compounds were calculated by the Kissinger method and Ozawa-Doyle method. According to the standard test method GJB 770A-97, the friction sensitivity, impact sensitivity, flame sensitivity and 5 seconds ignition point of the compound were measured, which demonstrated the compound had a certain degree sensitivity and [Cu(tza)2]n could be applied in potential energetic material. Thermal decomposition data of mixture of [Cu(tza)2]n and RDX demonstrates: the addition of the title complex makes the onset temperature and peak temperature of RDX shift downwards, and the thermal decomposition of RDX is accelerated due to the catalyst of the [Cu(tza)2], which can provide theoretical support to further performance study as the title complex is added to the propellant formulations to regulate the burning rate.
