Abstract

INTERACTION BETWEEN SOLVENT-SOLVENT MOLECULES IN A TERNARY MIXTURE AT DIFFERENT TEMPERATURES BY ULTRASONIC TECHNIQUE

*Sanjeev Rambhau Dudhat and Sonali Shankarrao Chine

ABSTRACT

The basic parameters like viscosity (η), density(ρ) and velocity (U) can be measured by ultrasonic Interferometer. From these three parameters various thermodynamical and acoustical parameters such as specific acoustic impedance (Z), Intermolecular free length (Lf), adiabatic compressibility „s (β) etc can be estimated using standard relations from measured values of Ultrasonic viscosities, densities and velocities in the wide range of concentrations at 350C, 400C and 450C temperatures for Acetone + Propanol-2 + chloroform tertiary system. The solvent-solvent interactions are studied on the basis of increase or decrease in ultrasonic velocity, density, viscosity and other derived acoustical parameters in terms of structure making and structure breaking tendencies of various solvent molecules.

Keywords: Density, ultrasonic interferometer, ultrasonic velocity, viscosity, water bath.
