用Union Giken RA-410温度跃变紫外可见分光光度计研究了二聚的四-对磺酸基-苯基卟啉铁[Fe(Ⅲ)TPPS_4)_D]与咪唑(Im)、2-甲基咪唑(MeIm)、2-乙基-4-甲基咪唑(EMIm)轴向配位快速反应动力学。提出了反应机理,研究了轴向配体和温度对反应的影响,应用Gauss-Newton-Marquardt方法求得基元反应的速率常数及活化参数。
The effects of dimerization of tetrakis-p-sulfonic acid-phenyl-porphyrin iron [Fe (Ⅲ) TPPS_4) _D] with imidazole (Im), 2- Imidazole (MeIm), 2-Ethyl-4-methylimidazole (EMIm) Axial coordination Fast reaction kinetics The reaction mechanism was proposed. The effects of axial ligand and temperature on the reaction were studied. The rate constants and activation parameters of the elementary reaction were obtained by Gauss-Newton-Marquardt method.
