ULTRASONIC INVESTIGATION OF MOLECULAR INTERACTIONS IN BINARY LIQUID MIXTURES AT 298K

Abstracts

Ultrasonic velocity, density and viscosity of a binary system of acrylonitrile in 1, 4-Dioxane have been measured at 298 K and 2 MHz. Experimental data of the ultrasonic sound velocity, density and viscosity have been used to calculate various acoustical parameters, such as adiabatic compressibility (β_a), intermolecular free length (L_f), free volume (V_f), excess values of adiabatic compressibility (βa^E), excess values of free length (L_f^E) and excess values of free volume (V_f^E). It is observed from these acoustical parameters that, weak intermolecular interactions are confirmed in this system. Dipole inducement in the system is found to be more predominant. The nonlinear behavior of all these parameters throws more light on the various interactions among the molecules.
