The data available in the literature and our recent data on vapour�liquid equilibrium (VLE), excess Gibbs energy, GE, and excess enthalpy, HE, for the homologous series of cyclopentanone + chloroalkane mixtures are examined in terms of the predictive group contribution models DISQUAC and UNIFAC. In our treatment, we present also how the structural effects and different types of molecular interactions are reflected by the thermodynamic excess properties of the mentioned series mixtures.

AbstractThe model proposed by Treszczanowicz and Benson (1985) is applied for the description and interpretation of excess enthalpy HE, excess volume VE and excess molar isobaric heat capacity CEp of the binary systems formed by 1-alkylamines and dialkyl-amines with n-alkanes. In the model, the self-association contribution is described by an athermal associated mixture model with the continuous mode of association of the Mecke–Kempter type and the equation of state contribution described by the Flory theory. The three self-association parameters: enthalpy, entropy and volume are valid over the whole homologous series of 1-alkylamines and dialkylamines. The equation of state interaction parameters are correlated for both series of mixtures with the structure of the component molecules by using the Kehiaian–Guggenheim group contribution method. The model predicts reasonably well HE as well as VE for both these classes of mixtures.
