Resumen:

A continuous linear association model for the excess Gibbs energy (gE) previously used for alcohol-alcohol solutions has been applied to binary nitrile-alcohol mixtures. The method of Hanks, Gupta and Christensen has been used to predict vapor-liquid equilibria (VLE) from heat of mixing (hE) data for these mixtures. Results are compared with those obtained for other models widely used in the literature. The predictions made using the new model agree well with the experimental VLE data.
