Abstract

The ultrasonic velocity (U), Density (ρ) and Viscosity (η) have been measured for three ternary liquid mixtures of Aniline + Cyclohexane + Ethyl methyl Ketone, Aniline + Cyclohexane + Dimethyl Ketone and Aniline + Cyclohexane + Iso-butyl methyl Ketone at 303K, 313K and 323K. The experimental data have been used to calculate the acoustical parameters such as adiabatic compressibility (β), free length (Lf), free volume (Vf), internal pressure (π), viscous relaxation time (τ)and Gibb’s free energy (ΔG)were evaluated. The obtained results support the occurrence of molecular association through intermolecular hydrogen bonding in these ternary liquid mixtures.
