Correlation Procedure

Liquid-liquid equilibrium and excess enthalpies at 25, 40 and 60 °C were measured for the 4-methylpentan-2-one-water system. Vapour-liquid equilibrium at 115 °C and 99.96 kPa, and excess enthalpies at 25, 40 and 60 °C were determined for the 4-methylpentan-2-one- 4-methylpentan-2-ol system. The data obtained were correlated together with those given in literature using the superposition of the Wilson and Redlich-Kister equation. The correlation procedure utilised also the data on excess enthalpy measured in a heterogeneous region.

Thermodynamic Excess

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.

Vapour pressures and vapour compositions of the liquid system water + acetic acid have been measured at 25 °C, 30 °C, 35 °C, 40 °C, and 45 °C in the whole range of compositions. The dimerization of acetic acid in the vapour being taken into account, the molar excess Gibbs function ḠE is derived from the measurements. Earlier measurements of the molar excess enthalpy HE are combined with the -GE values to give the molar excess entropy SE. The “symmetry rule” (Haase, 1951) concerning the composition dependence of ḠE, -HE, and S̄E has been confirmed.
