Abstract

The ultrasonic velocity and density of binary liquid mixtures of quinoline with o-xylene, m-xylene, and p-xylene have been measured over the entire range of composition at = 303.15, 308.15, 313.15, and 318.15 K. Using these data, various parameters like adiabatic compressibility (β), intermolecular free length ( ), and acoustic impedance ( ) and some excess parameters like excess adiabatic compressibility ( ), excess intermolecular free length ( ), excess acoustic impedance ( ), and excess ultrasonic velocity ( ) have been calculated for all the three mixtures. The calculated deviations and excess functions have been fitted to Redlich-Kister polynomial equation. The observed deviations have been explained on the basis of the intermolecular interactions present in these mixtures.
