Thermodynamics and Transport Properties of Ester with Cyclohexane in Pentanol at 303, 308 and 313K

Abstract

The ultrasonic velocity (U), density (ρ), viscosity (η) have been measured for the ternary mixtures of Methyl Benzoate and Cyclohexane with Pentanol at 303, 308 and 313K. From the experimental data, Adiabatic Compressibility (β), Free Length (L_F), Free Volume (V_F)), Internal Pressure (π_i), Relaxation time (τ), Acoustic Impedance (Z), Gibbs Free Energy (ΔG), Classical Absorption Coefficient (d/f²) and Cohesive Energy (H) have been calculated. In addition to that the excess values of certain above parameters are also evaluated. The excess properties have been used to discuss the presence of significant interactions between the component molecules in the ternary mixtures.
