Liquid-liquid equilibrium of aqueous polymer two-phase systems using the modified wilson equation

摘要

The modified Wilson equation, developed in a previous publication, for the excess Gibbs energyof aqueous polymer solutions, is extended to multicomponent mixtures. The model provides aflexible framework to correlate and predict phase equilibria of aqueous polymer two-phasesystems. The results obtained with the model are in fair agreement with the experimental data.
