“…To contribute to the knowledge of surface phenomena in binary organic mixtures, the present work reports surface tension values of ethylene glycol + benzyl alcohol at various temperatures. This work is a continuation of our recent works on the surface properties of ethylene glycol + alcohols, including ethylene glycol + ethanol, ethylene glycol + cyclopentanol and cyclohexanol, , and ethylene glycol + methyl cyclohexanols . Jimenez et al also reported the surface tension of ethylene glycol + 1-propanol and 1-butanol.…”

The paper presents the properties of mixtures of benzyl alcohol and ethylene glycol at the liquid/air interface. The properties were studied by surface tension measurements carried out at as a function of the mole fraction of benzyl alcohol at temperatures between (20 and 50)°C. It was shown that at constant temperature by the addition of benzyl alcohol the surface tension decreases and at constant composition by the increasing of temperature the surface tension decreases linearly. The surface entropies and enthalpies were calculated from experimental data. The surface composition of the mixture at a low concentration of benzyl alcohol was obtained from the extended Langmuir model. Values of the excess surface tension for mixtures were calculated and show a negative deviation from ideality.

“…The literature dealing with surface tension of aqueous binary mixtures is extensive, but for nonaqueous binary mixtures it is scanty. Recently, we have investigated the surface tension of nonaqueous binary mixtures. − In the present work, benzyl alcohol was chosen as the solvent, and cyclohexane, hexane, heptane, and nonane were chosen as the solute. The surface tension of binary mixtures was investigated at low concentration of alkanes because most of the surface tension changes in nonelectrolyte systems occur at very low concentration of the solutes, while surface parameters remain almost unchanged for high concentration.…”

Surface tensions of dilute solutions of cyclohexane, hexane, heptane, and nonane in benzyl alcohol were measured at various temperatures. Surface mole fractions were obtained from an extended Langmuir model. The results show that all of alkanes are surface active in benzyl alcohol and that their surface mole fractions are higher than their bulk mole fractions. The lyophobicity of solutes decreases with increasing temperature.

“…1-4. If the interactions between molecules of the components are relatively weak, the surface tension of the mixture is expected to deviate from linearity [5][6][7]. It is energetically more favourable for the component with the lower surface tension to be preferentially expelled from the bulk to the surface.…”

Results of measurement of surface tension on mixed solutions of methyl acetate and ethyl acetate with cyclohexanone and acetophenone are reported. The values are interpreted in terms of intermolecular interactions. Surface tension deviations from linear, additive values, show that the acetophenone interacts with either methyl or ethyl acetate less strongly as compared to cyclohexanone. Similarly ethyl acetate interacts less strongly with either acetophenone or cyclohexanone compared to methyl acetate. The results are interpreted in terms of the relative bulk and the polarizability of the interacting molecules.
