研究了三氯甲烷中咪唑（Ｉｍ）与氯代（对位单取代谷氨酸四苯基）卟啉铁（Ⅲ）（简记为ＦｅＬＧｌｕＣｌ）的轴向配位反应。用光度法测定了反应的平衡常数Ｋ，标准摩尔焓变△Ｈ０ｍ和标准摩尔熵变△Ｓ０ｍ。实验结果表明，反应（１）（见后）是熵和焓都降低的过程
The axial coordination reaction of imidazole (Im) with chloro (para-substituted monosubstituted glutamic tetraphenyl) porphyrin iron (Ⅲ) (abbreviated as FeLGluCl) in chloroform was studied. The equilibrium constant K, the standard molar enthalpy change △ H0m and the standard molar entropy change △ S0m were determined by spectrophotometry. The experimental results show that the reaction (1) (see below) is a process of both entropy and enthalpy reduction
