摘要
用碳酰肼、苦味酸与相应的金属盐在水溶液中反应制备出苦味酸碳酰肼钴、铜、铅含能配合物Co(CHZ)4(PA)2.3H2O、Cu(CHZ)4(PA)2.4H2O和Pb(CHZ)2(PA)2.4H2O(CHZ为碳酰肼,PA为苦味酸),通过元素分析和FT-IR分析对产物进行了分子式推测。用标准方法测定了含能配合物的撞击、摩擦和火焰感度,应用DSC和TG-DTG法测试了含能配合物对CL-20热分解过程的影响。结果表明,含能配合物都能够一定程度降低CL-20的起始分解温度和峰值,用Kissinger法和Ozawa-Doyle法获得了含能配合物/CL-20混合物的第一放热分解过程的活化能Ea和指前因子A,表明含能配合物Cu(CHZ)4(PA)2和Co(CHZ)4(PA)2使CL-20的热分解活化能由原来的222.8kJ/mol降至186.6kJ/mol和183.0kJ/mol。
Three kinds of energetic complexes, Co （CHZ）4 （PA）2· 3H2O,Cu （CHZ）· （PA）2 · 4H2O and Pb （CHZ）2 （PA）2 · 4H2O （CHZ = earbodihydrazide,PA ：picrie acid）, were synthesized with carbohydrazide, picric acid and corresponding metallic （Co, Cu, Pb） salts. The molecular formulas of these coordination compounds were derived by using elemental analyses and FT-IR techniques. The friction, impact and flame sensitivities of the complexes were tested followed by the standard methods. The effects of the energetic complexes on the thermal decomposition of CL-20 were studied by means of DSC and TG DTG techniques. The results show that the addition of those complexes make the onset temperature and peak temperature of CL-20 shift to low temperature. The kinetic parameters Ea and A of the first exothermic decomposition process for complexes/CL-20 mixture were calculated by Kissinger＇s method and Ozawa-Doyles method. Cu（CHZ）（FA） and （CHZ）（PA） make the Eavalue of the exothermic processes of CL-20 decrease from 222.8k J/mol to 186.6k J/mol and 183. 0kJ/mol.
