摘要: 研究了二氯甲烷溶液中二乙胺(L)与氯合(meso-四-间甲基苯基卟啉)铁(Ⅲ)的轴向配位反应.用光谱法测得不同温度下反应的平衡常数,求得(m-CH3)TPPFe(Ⅲ)Cl+L=(m-CH3)TPPFe(Ⅲ)Cl·L反应的标准摩尔焓和摩尔熵.同时,对反应的动力学与反应机理进行了研究.也研究了反应物和产物的紫外可见光谱,并讨论了取代基及轴向配体对铁卟啉紫外可见光谱的影响。

Abstract: The axial coordination reaction of tctra(mcta-mcthylphcnyl) porphinatoiron(Ⅲ) chloride with dicthylaminc(L) in dichloromcthanc was reported in this paper.The equilibrium constants were measured by spectral technique and the standard change of molar enthalpy(ΔrHmø) and molar entropy(ΔrSmø) of the reaction were calculated.On the other hand,the kinetics of the reaction was also studied and the mechanism was supposed as follows:Fe(Ⅲ)P+L Fe(Ⅲ)PL Last,the UV-Vis spectra of meta-substitute tetraphenylporphinato iron(Ⅲ) chloride were measured by means of Bekman Du 8B Spcctrophotomctcr and the effects of the substitucnts in the porphyrin and axial ligand to the spectra were discussed.
Keywords: tetraphenylporphinato iron(Ⅲ)chloride  equilibrium constant UV-Vis spectra  kinetics
