Abstract: The excess adiabatic compressibility (βE), excess free length (LfE), excess free volume (VfE) and excess internal pressure (πiE) have been investigated from density, ultrasonic velocity and viscosity measurements for three ternary mixtures of methyl benzoate + cyclohexane + 1-propanol, methyl benzoate + cyclohexane + 1-butanol, methyl benzoate + cyclohexane +1-pentanol and methyl benzoate + cyclohexane + 1-hexanol at 303, 308 and 313 K and atmospheric pressure, respectively over the entire range of composition. From the experimental data, adiabatic compressibility (β), free length (Lf), free volume (Vf)), internal pressure (πi), have been calculated. The results are discussed in terms of the molecular interactions between the components of the mixture.
