Vapor–liquid equilibria of cyclohexane–cis-decalin mixtures were determined at 25 °C in a circulation still. Excess Gibbs free energies derived from the experimental results are in reasonable agreement with values calculated from the theory of Flory.

Densities and vapor-liquid equilibria were determined for tetrahydrofuran with propan-1-ol and propan-2-ol systems at 298.15 K. From the experimental results, excess molar volumes and excess Gibbs free energies were calculated. Information could be obtained from the possible interaction between both chemical species in the two systems. The Prigogine–Flory–Patterson method was applied to calculate excess molar volumes. Liquid activity coefficients were calculated and correlated with different expressions existing in the literature. Keywords: excess molar volumes, vapor–liquid equilibria, activity coefficients, excess Gibbs free energies, tetrahydrofuran, propan-1-ol, propan-2-ol.

Vapor–liquid equilibria for the system benzene – m-xylene were measured in a circulation still at 25, 37, and 50 °C. Excess free energy data were analyzed in terms of Flory's theory of non-polar mixtures.

Molar excess enthalpies and volumes of the systems cyclopentane – cis-decalin and cyclopentane – trans-decalin at 25 °C were determined by direct calorimetric and dilatometric measurements. Excess Gibbs free energies, also at 25 °C, were obtained from a study of the vapor–liquid equilibria. The excess properties of these cyclopentane systems are compared with those of their cyclohexane counterparts, and are interpreted in terms of the theory of Flory.

The vapor–liquid equilibria of the 4 binary systems formed by mixing methanol with n-butanol, isobutanol, sec-butanol, and tert-butanol were investigated at 25 °C in a dynamic still with circulation. The results were used to calculate the molar excess Gibbs free energies. For the three systems containing isobutanol, sec-butanol, or tert-butanol, molar excess enthalpies and volumes were also determined (mainly at 25 °C) by direct calorimetric and dilatometric techniques. The behavior of the excess properties is discussed with reference to differences in the hydrogen bonding and in the shapes of the component molecules.
