Abstract

Densities and ultrasonic velocities of binary liquid mixtures of cylohexane with carbitols 2(2-methoxyethoxy)
ethanol (metylcarbitol), 2(2-ethoxyethoxy)ethanol (ethylcarbitol), and 2(2-butoxyethoxy)ethanol (butylcarbitol)
have been measured at 308.15 K. The observed data have been utilized to calculate various acoustical parameters
such as Isentropic compressibility (KS), Intermolecular free length (Lf), and acoustic impedance (Z). The various
excess properties including excess ultrasonic velocity (uE), excess acoustic impedance (ZE), excess isentropic
compressibility (Ks
E) and excess intermolecular free length (Ls
E) were calculated. The results were discussed in
terms of the existence of intermolecular interactions between the components in the liquid mixtures under study.
