氯苯甲酸在水-DMF混合溶剂中和在气相中的质子迁移反应比较

A Study of the Proton Transfer of Chloro substituted Benzoic Acids in Water DMF Mixtures Compared With the Same Process in the Gaseous Phase

将在水 DMF混合溶剂中从氯苯甲酸到苯甲酸的质子迁移过程与在气相中的同一过程进行了比较 .用一个热力学循环计算了在从气相初始状态到混合溶剂某一组成X时该质子迁移过程的热力学函数的变化 ,即δΔPig→X.这一项的值被作为质子迁移过程中氯苯甲酸分子。

A study on the proton transfer process from chloro-substituted benzoic acids to benzoic acid in H2O-DMF mixtures compared with the same process in the gaseous phase is presented. A thermodynamic cycle was used to calculate changes of some thermodynamic properties for a proton transfer process in a solvent X which refers to a gaseous initial thermodynamic state, i. e. δΔPig&rarrx. Values of this term have been assumed as a measure of 'environmental' interactions of the proton transfer process among molecules, anions and solvent.
