【Abstract】 An approach based on the molecular topology is used to study the quantitative relationship between salt effeet constant of five aromatic hydrocarbons in the simple salt solution and its molecular structure. Their results are compared with the calculated results of Debye-McAulay (DMT) and Conway-Desnogers-Smith electrostatic theories (CDST), Mcdevit-Long internal pressure theory (IPT) and modified internal pressure theory (XIPT). It is verified that the new model approximates to the experimental value better.更多还原
