Abstract: The Ultrasonic velocity(U), density(ρ), and viscosity(η) have been measured experimentally for the ternary liquid mixtures of 3(meta) methoxy phenol(MMP), 1 propanol and n hexane at various temperatures viz., 303 K, 308 K and 313 K at constant frequency of 2 MHz. for different concentrations ranges from 0.001M to 0.01M. The thermodynamic and acoustical parameters such as adiabatic compressibility(β), Rao constant(R), absorption coefficient (α/f2 ), internal pressure(πi), cohesive energy(CE), free volume(Vf), free length(Lf), acoustic impedence(z), available volume(Va), viscous relaxation time and Lenard Jones potential were calculated from the experimental data. The various excess properties including excess Ultrasonic velocity, excess acoustic impedence, excess free length, excess adiabatic compressibility, excess free volume and excess internal pressure were also computed. The variation of these excess parameters with respect to concentration and temperatures have been discussed in the light of molecular interaction. The molecular interactions were predicted based on the results obtained for ultrasonic velocities of different concentrations of the ternary mixtures at different temperatures.
