Densities, ρ, and molar excess volumes, V E , for binary and ternary systems of (1,4-dioxane, 1-propanol or 2-propanol, and 1,2dichloroethane) were measured over the whole composition range, at T = [288.15, 298.15, 308.15, and 318.15] K, and atmospheric pressure. The density measurements were performed using an Anton Paar vibrating U-tube densimeter. The binary mixtures of 1-propanol or 2-propanol with 1,4-dioxane present positive V E values over the whole composition and working temperature ranges, whereas with 1,2-dichloroethane even negative V E values are observed at higher alcohol mole fraction and at lower temperature. The V E magnitude, for the alkanol containing binary mixtures, increases as the temperature increases and decreases for 1,4-dioxane + 1,2-dichloroethane. The experimental V E data, for all the binary mixtures, were fitted to the Redlich−Kister equation. For all the ternary mixtures, the excess molar volumes are found to be positive and increase with the temperature increase. The experimental ternary V E values were fitted to the Cibulka equation. The capability of the Prigogine−Flory−Patterson theory (PFP model) in predicting excess volume, for binary mixtures, was tested. Comparison of the experimental V E values with the PFP calculations, for all the binary mixtures, at 298.15 K, was graphically presented.

“…Studies of the dielectric properties of liquid mixtures at static and optical frequencies are important and desirable for achieving a theoretical and practical understanding of the nature of intermolecular forces and their resulting structures in the mixture. − Many experiments have been carried out to investigate the static dielectric permittivity and other physical and physicochemical behavior of binary mixtures; − however, reliable experimental data over a wide range of compositions for different liquid mixtures are still important and required. Among the many binary mixtures that have been investigated, hydrogen-bonded systems such as ketone–alcohol are of particular interest. − …”

Relative permittivities, refractive indices, and densities were measured for binary liquid mixtures of cyclohexanone with 1-alkanols (ethanol, 1-butanol, 1-hexanol, 1-octanol, and 1-decanol) in the mole fraction range of (0 ≤ x 2 ≤ 1) at T = 298.15 and p = 101.3 kPa. Another comparative dielectric study was performed on the (cyclohexanone or cyclopentanone + cyclohexanol or cyclohexane) mixtures at the mentioned temperature and pressure. The experimental data were analyzed in terms of the various approaches in order to obtain information about the intermolecular interactions and the mixture structure. The excess properties of different physical quantities confirm the formation of hydrogen-bond structure in these mixtures. For the studied systems, negative excess permittivities and excess Kirkwood correlation factors were obtained, indicating a reduction of the number of effective dipoles in the binary mixtures.
