Isentropic compressibility for binary mixtures of propylene carbonate with benzene and substituted benzene

Abstract

Ultrasonic velocities (u) for binary mixtures of propylene carbonate (PC) (1) with benzene and substituted benzenes (2) viz. benzene, ethylbenzene, o-xylene and p-xylene have been measured at 288.15-308.15 K over the entire range of composition. The experimental values of ultrasonic velocities (u) have been utilized to calculate isentropic compressibility (Ks), intermolecular free length (Lf), acoustic impedance (Z).
