Abstract

A method for estimating Wilson parameters on the basis of solubility parameters and molar volumes has been adopted to correlate vapor–liquid equilibria of polar mixtures such as binary systems containing ethers, ketones, ethanol, and water. The correlation performances are examined and discussed.
