Measurements of speeds of sound, u, have been made in binary mixtures of anisole (C6H5OCH3) with dichloromethane (CH2Cl2), 1,2-dichloroethane (CH2ClCH2Cl), trichloroethene (CHClCCl2), tetrachloroethene (CCl2CCl2), and cyclohexane (c-C6H12) at T = 303.15K. The densities rho of the present mixtures have been calculated at T = 303.15 K using the available data on excess molar volumes V-m(E), whereas the densities rho(double dagger) of the pure component liquids have been measured at T = 303.15 K with a pyknometer, and these results are reported. Values of a have been used to calculate the apparent excess speeds of sound Delta u and the isentropic compressibilities res for these mixtures. The excess isentropic compressibilities kappa(S)(E), have also been calculated from the values of kappa(S) The kappa(S)(E) has been found to be slightly positive for {xC(6)H(5)OCH(3) + (1-x)CH2ClCH2Cl}, and {xC(6)H(5)OCH(3) + (1 - x)CCl2CCl2}, and slightly negative for {xC(6)H(5)OCH(3) + (1 - x)CHClCCl2). The kappa(S)(E) is slightly positive at low mole fractions of C6H5OCH3, and negative at high mole fractions of C6H5OCH3, for {xC(6)H(5)OCH(3) + (1-x)c-C6H12). For {xC(6)H(5)OCH(3) + (1 -x)CH2Cl2), kappa(S)(E) is very slightly positive at low mole fractions of C6H5OCH3, and it shows a negative trend at high mole fractions of C6H5OCH3. Values of kappa(S)(E) for the various mixtures are discussed in the light of intermolecular interactions between the components.
