Abstract

ULTRASONIC STUDIES ON MOLECULAR INTERACTION IN TERNARY LIQUID MIXTURE OF DIMETHYL SULPHOXIDE AT DIFFERENT FREQUENCIES

Dr. A. Suryanarayana Reddy, E. Chandra Shekar and Satyanarayana*

ABSTRACT

The density (ρ) and ultrasonic velocity (U) for ternary mixture of dimethyl sulphoxide, benzoic acid and Ethyl Glycol at different frequencies (2MHZ, 4MHz, 6MHZ, and 8MHZ) have been measured at 308K. Ultrasonic technique is used for studying the acoustic properties for a number of systems including liquids, low melting solids, dilute solutions of organic liquids and their mixtures. Ultrasonic studies in organic liquids and their binary mixtures have been of considerable research interest during the last few decades. These data have been used to compute adiabatic compressibility (Ks), intermolecular free length (Lf), acoustic Impedance (Z), molar volume (Vm), molar sound velocity(R), molar compressibility (B), available volume (Va), Lennard Jones potential repulsive term exponent(n), relative association(RA).

Keywords: Molar volume, dimethyl sulphoxide, interaction parameter, ternary mixture.
