Thermophysical and sonochemical behaviour of binary mixtures of decan-1-ol with halohydrocarbons at (T=293.15 and 313.15) K
Densities and ultrasonic velocities of binary mixtures of decan-1-ol with 11,2-dichloroethane, 1,2-dibromoethane, and 1,1,2,2-tetrachloroethene have been measured over the entire range of composition at T = (293.15 and 313.15) K and at atmospheric pressure. From these results, the excess molar volumes, molar free volumes, excess molar isentropic compressibilities, limiting excess partial molar volumes, and isentropic compressibilities, intermolecular free lengths, and available volumes by three methods, thermal expansion coefficients, parameters related to space-filling ability, intermolecular free lengths, and molecular radii have been calculated. The experimental ultrasonic velocities have been analyzed in terms of the ideal mixture relations of Nomoto and Van Dael, Jacobson's free length, Schaaff's collision factor, Flory's statistical, and Prigogine-Flory-Patterson theories and thermoacoustical parameters.
