Thermodynamics of alcohol solutions

Abstract

An associated-solution model, based on the new local composition model (see Nagata et al. Thermochim. Acta, 224 (1993) 59–69), is presented. The association parameters of pure alcohols have been estimated using ethers as homomorphs of alcohols. The model shows a good performance in representing vapour-liquid equilibria, coexistence curves, and excess enthalpies for binary alcohol mixtures and in predicting ternary vapour-liquid and liquid-liquid equilibria and excess enthalpies for many alcohol mixtures from binary parameters.
