Abstract
The UNIQUAC associated-solution model has been applied to reproduce va pour-liquid equilibria and excess molar enthalpies for binary mixtures containing one alkanoic acid and one alkanol and then to predict tern ary excess molar enthalpies for acetic acid + methanol + tetrachlorome thane. Furthermore, the model has been modified to include additional parameters in order to obtain a better correlation of vapour-liquid eq uilibria of strongly non-ideal mixtures involving at least one alkanol . The calculated results agree well with the experimental values for m any systems studied.
