【摘要】 水热条件下合成了一个四唑含能配合物[Co（pzta）（H₂O）₂]（pzta=5-吡嗪基四唑）。运用TG-DSC热分析仪研究了配合物的热分解行为;在非等温条件下,采用Kissinger’s和Ozawa-Doyle’s两种方法,对配合物进行了非等温动力学研究,得到它的表观活化能（E=153.63 k J mol-1）。利用DSC技术分析了配合物对AP和HMX热分解行为的影响,结果表明:配合物的加入对于HMX的放出的热量和峰温影响不大;使AP的分解峰温提前不多,但是加入配合物后呈现出的剧烈放热过程,放热量增加,因此配合物对AP具有较好的催化燃烧效果。更多还原

【Abstract】 A energetic complex[Co（ pzta）（ H₂O）₂]（ pzta=5-（ pyrazinyl） tetrazole） was prepared by hydrothermal synthesis.Thermal decomposition character of the complex was studied by means of TG and DSC thermal analyzer. Under non-isothermal condition,the Kissinger’s and Doyle Ozawa’s two methods were applied to determine the kinetic parameters,as the apparent activation energy（ E =153. 63 k J mol-1）. The influence of thermal decomposition behavior for AP or HMX is analyzed using the DSC technology,the results are as follows: the heat and peak temperature of HMX change small; and the peak temperature of AP decomposition slightly lower,but hybrid system presents a rapid exothermic process and the heat release increase,so the complex has better catalytic combustion effect for AP.更多还原
