合成了标题化合物,用元素分析、IR、TG-DTG、XRD等方法对其进行了表征。结果显示该化合物仍保持杂多阴离子的Keggin结构的基本特征。同时,采用TG-DTG技术研究了标题化合物在氮气气氛中的热分解机理及非等温动力学,运用Coats-Redfern积分法、胡荣祖-高红旭-张海法、Achar-Brindley-Sharp-Wendworth微分法对配合物的非等温动力学数据进行分析,得出了热分解反应的机理函数、动力学参数以及3步分解反应的活化能E和lnA。
The title compound was synthesized and characterized by elemental analysis, IR, TG-DTG and XRD. The results show that the compound still retains the basic characteristics of heteropolyankene Keggin structure. At the same time, the thermal decomposition mechanism and non-isothermal kinetics of the title compound under nitrogen atmosphere were studied by TG-DTG technique. The complex structure was characterized by Coats-Redfern integral method, Hu Rongzu-Gao Hongxu-Zhang Haifa and Achar-Brindley-Sharp-Wendworth differential method The kinetic parameters and the activation energies E and lnA of the three-step decomposition reaction were obtained.
