EXCESS ACOUSTICAL STUDIES IN LIQUID MIXTURES OF ANILINE WITH O-XYLENE AT DIFFERENT TEMPERATURES T= (303.15KK, 308.15K, 313.15K and 318.15) K

摘要

Excess acoustical parameters such as excess intermolecular free length (LfE), excess adiabatic compressibility (βE), excess acoustic impedance (ZE) and excess ultrasonic velocity (UE) have been computed from experimentally determined values of densities(ρ), ultrasonic velocities(u) and viscosities(η) in binary liquid mixtures containing aniline with o-xylene at temperatures T=(303.15,308.15,313.15 and 318.15)K. These results are fitted to the Redlich-Kister polynomial equation. These results have been explained on the basis of intermolecular interactions in liquid mixtures.
