An approach based on the molecular topology is used to study the relationship between salt effect constand of chlorobenzene system in the aqueous salt solution and its molecular structure,and an equation is developed which can be used to characterize the structure-property relationship and to predict the salt effect constand of chlorobenzene system in the aqueaus salt solution. These results are compared with the calculated results of Debye-McAulay and Conway-Desnogers-Smith electrostatic theories; Masterton-Lee Scaled particle theory, Mcdevit-Long internal pressure theory and modified internal pressure theory. It is verified that the new model coincides with the experimental value better.
