Molecular Interaction Study on Binary Mixture of Phenol in Dioxane, Methanol and Acetonitrile at 303 K

摘要

The ultrasonic velocity (U), density (ρ) and viscosity (η) at 303 K have been measured in the binary system of phenol in dioxane, methanol and acetonitrile. The acoustical parameters such as adiabatic compressibility (β), free length (L_f), free volume (V_f), internal pressure (π_i), Wada's constant (W), Rao's constant (R) and acoustical impedance (Z) are calculated. The results are interpreted in terms of molecular interaction between the components of the mixtures.
