Calculation of Solubility Parameter for Liquids Hu Fuxin (Chemistry and Chemical Engineering College, Xinyang Normal University, Xinyang Henan 464000) Abstract On the basis of the definition for solubility parameter, the correlation equation is used for vaporization enthalpy in conjunction with critical property and eccentric factor. Solubility parameters of 50 kinds of solvents have been calculated. The results of calculation for the solubility parameters werecompared with those in the reference literature, the average relative error is 1.98%.
