摘要
用分光光度法研究了铜 ( )与四苯基卟啉在溶剂 DMF中生成 Cu TPP的动力学以及镉 ( )离子对该反应的催化作用 ,提出反应机理 ,并研究了温度及溶剂效应对反应动力学参数的影响 ,求得基元反应的活化参数 △ H≠m、△S≠m 及前置平衡步的△HΘm、△SΘm。
Kinetics of formation of tetraphenylporphrinatocopper(Ⅱ) in DMF had been studied spectrophotometry in the presence of cadmium(Ⅱ) ion.The effect of solvent on the reactions were discussed.The mechanisms of reaction were proposed.The activation parameters △H≠ m、△S≠ m [WT5”BZ]of elementary step,the standard molar enthalpy change △HΘ m and the standard molar entropy △SΘ m change of pre-equilibrium step had been calculated.
