Abstract

The ultrasonic velocity(U), density (ρ) and viscosity (η) of pure solvents and binary mixtures of Anisole and Methyl Isobutyl Ketone have been investigated at three different temperatures 303.15K, 308.15K and 313.15K and correlated with concentration. The observed data have been used to evaluate some of the thermo acoustical parameters such as adiabatic compressibility (βa), intermolecular free length (Lf), internal pressure (πi), acoustic impedance (Z), available volume (Va), relaxation time (τ), molar volume (Vm) and Gibb’s free energy (∆G), Lennard Jones potential repulsive term exponent(n) to elucidate the molecular association in the mixture. The variation of these parameters with concentration of solute indicates the nature of interaction present in the binary mixture.
