Abstract
Densities ρ have been measured from 29815 to 31315 K at atmospheric pressure over the entire composition range for binary mixtures of benzyl alcohol with 12dichloroethane 111trichloroethane 1122tetrachloroethane trichloroethylene and tetrachloroethylene Further the speeds of sound in these mixtures were also measured from 30315 to 31315 K The experimental density data were used to compute excess molar volumes V E which were compared with the Redlich–Kister and Hwang equations Excess speeds of sound u E isentropic compressibilities κ S and excess isentropic compressibilities kappa StextE were evaluated from experimental speed of sound and density data Moreover the experimental speeds of sound were compared in terms of theoretical models proposed by Schaaff’s collision factor theory and Jacobson’s free length theory The experimental and derived properties are discussed in terms of intermolecular interactions between component molecules
