Excess Transport Properties of Binary Mixtures of Quinoline with Xylenes at Different Temperatures

الملخص EN

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 T = 303.15, 308.15, 313.15, and 318.15 K.

Using these data, various parameters like adiabatic compressibility (β), intermolecular free length (Lf), and acoustic impedance (Z) and some excess parameters like excess adiabatic compressibility (βE), excess intermolecular free length (Lf E), excess acoustic impedance (ZE), and excess ultrasonic velocity (uE) 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.
