STUDY OF MOLECULAR INTERACTIONS IN THE BINARY LIQUID MIXTURES FROM ACOUSTIC AND THERMODYNAMIC PARAMETERS AT 303K AND 2 MHz FREQUENCY

Abstract

The ultrasonic velocity, density and viscosity at 303K have been measured in the binary systems of acrylonitrile with 1, 4-Dioxane. From the experimental data, various acoustical parameters such as adiabatic compressibility (βa), intermolecular free length (Lf), specific acoustical impedance (Z), free volume (Vf), internal pressure (πi) and relaxation time (τ) 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 the system. The results are interpreted in terms of molecular interaction between the components of the mixture.
