The regular solution model (the Hildebrand-Scatchard equation) coupled with the Flory-Huggins equation has been extended by using the local volume fraction of Wilson to be applicable to correlate vapor-liquid equilibria (VLE) of polar mixtures. The extended regular solution model with the local volume fraction (RSM-L) has been applied to ethanol + hydrocarbon binary mixtures in a previous study and it is found that the model can be correlate VLE of the mixtures. In this study, as a continuation, RSM-L is adopted to correlate VLE of other polar binary mixtures containing ethers, ketones and water and its applicability is examined and discussed.
