摘　　要：用光度法研究了八乙基卟啉钴（ＯＥＰＣｏ）与咪唑、吡啶、γ－甲基吡啶、正丙胺、乙腈、三乙胺轴向配位反应的热力学，测定了平衡常数和组成比．结果表明：ＯＥＰＣｏ与这些有机碱均生成１：１的配合物．配位能力的大小为咪唑＞正丙胺＞γ－甲基吡啶＞吡啶＞乙腈＞三乙胺．A thermodynamic study is reported for the axial coordination of octaethylporphinatocobalt (OEPCo) with imidazole, pyridine, γ-methylpyridine, n-propylamine, triethylamine, acetonitrilr in toluene. Equilibrium constants and component ratio of reaction Were measured by spectrophotometric method. The standard molar enthalpy change ()and standard molar entropy change() and standard molar free energy () of reaction were calculated. Experiment results demontrate that all these bases reat with OEPCo to from 1: 1 adduct in toluene.
