The molecular interaction studies in the binary liquid mixtures of two aliphatic alcohols with 1, 4-dioxane has been carried out at 308 K using ultrasonic technique. The ultrasonic velocity, density and viscosity at 308 K have been measured in the binary systems of 1, 4-dioxane and ethanol with methanol. From the experimental data, various acoustical parameters such as adiabatic compressibility (βa), intermolecular free length (Lf), free volume (Vf) and internal pressure (Πi) were calculated. It has been observed that, weak dispersive type intermolecular interactions are confirmed in the systems investigated. Dipole inducement is found to be more predominant in methanol system. The results are interpreted in terms of molecular interaction between the components of the mixtures.

Abstract


The molecular interaction studies in the binary liquid mixtures of two aliphatic alcohols with 1, 4-dioxane has been carried out at 308 K using ultrasonic technique. The ultrasonic velocity, density and viscosity at 308 K have been measured in the binary systems of 1, 4-dioxane and ethanol with methanol. From the experimental data, various acoustical parameters such as adiabatic compressibility (βa), intermolecular free length (Lf), free volume (Vf) and internal pressure (Πi) were calculated. It has been observed that, weak dispersive type intermolecular interactions are confirmed in the systems investigated. Dipole inducement is found to be more predominant in methanol system. The results are interpreted in terms of molecular interaction between the components of the mixtures.
