Thermophysical and sonochemical behavior of binary mixtures of hexan-1-ol with halohydrocarbons at 303.15 K

Abstract

Densities and ultrasonic velocities of binary mixtures of hexan-1-ol with 1,2-dichloroethane, 1,2-dibromoethane and 1,1,2,2-tetrachloroethene have been measured over the entire range of composition at 303.15 K at the atmospheric pressure. From these experimental data, the excess molar volumes, molar free volumes, molar isentropic compressibilities, limiting excess partial molar volumes and isentropic compressibilities; deviations in ultrasonic velocity, molecular radii, Rao's molar sound functions, parameters related to space-filling ability, Beyer's parameters of non-linearity, available volumes and intermolecular free lengths by three methods have been estimated. The excess functions have been fitted to the Redlich–Kister polynomial functions and the results have been analyzed in terms of Nomoto's relation (N), Van Dael's relation (VD), Jacobson's free length theory (FLT), Schaaffs' collision factor theory (CFT), thermoacoustical parameters (TAP) and Prigogine–Flory–Patterson theory (PFP).
