Article Description

This communication reports two unique relationships for (1) Flory-Huggins interaction parameter (χ) and (2) vapor pressure of solvent (P), which explicitly show their composition dependency. There is no empirical constant in the proposed relationships, and no trial and error and/or data-fitting optimization is required for determination and/or correlation of vapor pressure and Flory-Huggins interaction parameter. A straightforward computational technique for implementation of models is provided. For a number of systems, the calculated data have been compared and evaluated against experimental ones and the reliability and accuracy of proposed relationships was assured. IARD (%) values on the order of 0.05 demonstrate the accuracy of the proposed method.
