Volumetric properties of binary liquid mixture of cyclopentyl methyl ether with 1-pentanol at 298.15 k temperature

Abstract

The densities (ρ) and ultrasonic speeds (u) of Cyclopentyl methyl ether, 1- Pentanol and their binary mixture with the whole composition range have been measured at 298.15 K. From the experimental data the excess molar volume (VE), deviations in isentropic compressibility (∆ks), deviations in ultrasonic speed (∆u), deviations in acoustic impedance (∆Z) have been determined. The sign and magnitude of these parameters were found to be sensitive towards interactions prevailing in the studied system. Moreover, VE values were theoretically predicted by using Flory’s statistical theory. The variations of derived parameters mentioned above with composition offer a convenient method to study the nature and extent of interactions between the component molecules of the liquid mixture not easily obtained by other means.
