An expression for the heat of mixing (h /SUP E/ ) of binary mixtures based on the assumption of the continuous linear association of both components is fitted to experimental h /SUP E/ data of alcohol-alcohol binary mixtures to determine the adjustable parameters. By use of these parameters, either isothermal or isobaric vapor-liquid equilibrium data are predicted following the method of Hanks, Gupta, and Christensen for 21 binary systems for which VLE and h /SUP E/ data have been found in the literature. The predictions obtained agree well with the experimental vapor-liquid equilibrium values even when the temperature difference between VLE and h /SUP E/ data is large.
