Experimental Values

Excess molar volumes and excess refractive indices of the n-octanol + 1,4-dioxane + 2-butanol system and the three corresponding binary mixtures have been determined at 298.15 K by measuring densities and refractive indices. Different expressions exist in the literature to predict these excess properties from binary data. An estimation of excess molar volumes is also evaluated using a modified Heller equation which depends on the refractive indices of the mixtures. A comparison of the predictions of different methods with the experimental values of the physical properties has been made.Key words: excess molar volumes, densities, refractive indices, n-octanol, 1,4-dioxane, 2-butanol, ternary system.

Abstract Intermolecular associations in liquid systems of non-polar and slightly polar compounds were studied through excess molar volumes (VME), and excess dielectric properties (εE and nD2E) for mixtures of carbon tetrachloride (CCl4) with benzene (C6H6), toluene (C6H5CH3), and p-xylene (p−(CH3)2C6H4). These excess properties were calculated from measurements of density (ρ), static permittivity (ε), and refractive index (nD) over the whole range of concentrations, at 298.15 K. The values of the excess dielectric properties for these mixtures were fitted in two different ways, one through least squares using the Redlich–Kister equation and the other using a model developed to explain deviations from ideality. The first fit was found to be descriptive while the second gave the equilibrium constant values for the interaction products actually formed in the mixtures and the respective electronic polarizabilities and dipole moments, indicating the existence of interaction products.

From experimental densities, viscosities, and refractive indexes for the acetylacetone + 1-pentanol, + 2-Pentanol, + isoamyl alcohol, and + tert-amyl alcohol systems at 298.15 K, the excess molar volumes, excess viscosities, excess molar free energies of activation of flow, and excess internal pressures were calculated over the whole concentration range. Conclusions about the molecular interactions in these mixtures were drawn from the variations of the excess functions with the composition.

The ternary excess properties were fitted to the polynomial equation of Cibulka. The experimental results were also compared with those predicted by the empirical equations of Redlich–Kister, Tsao–Smith, Kohler, and Colinet.

Excess viscosities, excess volumes, and excess free energies of activation for flow of the binary mixtures containing propionic acid with aniline, o-toluidine, o-anisidine, and o-chloroaniline were determined at five different temperatures from density and viscosity measurements. Based on the Regular Solutions Theory, the empirical parameter θ was calculated; this parameter is related to the viscosity, and also denotes the extent of the non-ideality of the system. The results obtained suggest the existence of acid–base interactions, as well as the formation of 1:2 complexes for the three first mixtures, and 2:1 complexes for o-chloro-aniline + propionic acid. The extent of the specific interaction decreases with an increase in the strength of the base, and increases with an increase in the dipole moments. The equatioin [Formula: see text] is proposed for predicting the mole volume of the mixtures, V, at any composition, Xi, as a function of the mole volumes of the pure components, Vi. Key words: binary mixture, excess properties, predicting mole volumes, propionic acid.
