Densities (rho) have been measured from 298.15 to 313.15 K at atmospheric pressure over the entire composition range for binary mixtures of benzyl alcohol with 1,2-dichloroethane, 1,1,1-trichloroethane, 1,1,2,2-tetrachloroethane, trichloroethylene and tetrachloroethylene. Further, the speeds of sound in these mixtures were also measured from 303.15 to 313.15 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 (kappa (S) ) and excess isentropic compressibilities () 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.
