Thermodynamics of associated solutions: New expressions for the excess Gibbs free energy and excess enthalpy of mixing of alcohol-solvent systems

This article presents new equations based on a continuous linear association model used by Kretschmer and Wiebe. The new equations are used to reduce experimental vapor-liquid equilibrium and excess enthalpy of mixing data for solutions of alcohols and active solvents. The new equations give an excellent representation of the experimental results and are able to predict equilibrium data for ternary alcohol-solvent systems with good accuracy.
