关于氯代苯在盐水溶液中的活度系数的研究

Study on the Activity Coefficients of Chlorbenzene in Aqueous Salt Solutions

运用拓扑理论探讨了氯代苯在盐水溶液中的盐效应常数ks 与氯代苯和盐结构之间的定量关系 ,给出了新的计算方法 ,也计算了盐效应常数ks 的各种理论值 ,并与实验值进行了比较 ,证实了新方法的计算值最接近实际 。

an approach based on the molecular topology is used to study quantitative relationship between salt effect constant of five aromatic chlorbenzene in the salt solution and its moledcular structure.These results are compard with the calculated results of DebyeMcAulay(DMT) and comway-Desnogers-Smith electrostatie(CDST)theeries,Mcdevit-Iong ineermal pressure theory(IPT) and modified internal pressure theory(XIPT).It is verified that new mdel approximates to the experiment value better.
