Abstract—Ultrasonic velocity, density and viscosity values have been measured at 298 K in the two binary systems of 1,4-dioxane with ethanol and methanol. From these data, acoustical parameters such as adiabatic compressibility, free length, free volume, relaxation time, specific acoustical impedance, molar volume, Rao’s constant, Wada’s constant and enthalpy are evaluated. From the properties of these acoustical parameters, the nature and the strength of interactions in these binary systems are discussed. 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.

Index Terms—Molecular interactions, specific acoustical impedance, molar volume, Rao’s constant, Wada’s constant, enthalpy and binary liquid mixtures.
