The application of thermogravimetry(TG) to the decomposition kinetics of [Co(py)_4Cl_2](py=pydine)

通过二氯四吡啶合钴(Ⅱ)配合物晶体的制备,以及X射线晶面探测和红外光谱进行的结构确认,报道了利用热重分析技术对配合物进行热分解行为表征及热分解动力学研究的过程:利用Ozawa-Flynn-Wall(OFW)动力学分析方法,对配合物的热分解进行了动力学研究,并计算了反应活化能.

A complex of pyridine was synthesized and characterized by using Rigaku-Raxis-IV X-ray diffractometry,spectroscopic analysis and thermal analysis.The crystal of [Co(py)_4Cl_2](py = pyridine) belongs to tetragonal system.The thermal decomposition kinetics was studied by using Ozawa-Flynn-Wall analysis and the kinetic parameters were obtained.
