Narayana22012122The viscosities, densities and ultrasonic velocities of binary liquid mixtures of Anisaldehyde with o-xylene, m-xylene and p-xylene have been measured at temperatures (303.15, 308.15, 313.15 and 318.15) K over the entire range of mole fraction. These data have been used to evaluate adiabatic compressibility (β), free volume (V_{f}), free length (L_{f}) internal pressure (π) and enthalpy (H). Excess values of above parameters have also been calculated and fitted to the Redlich-Kister polynomial relation to estimate the binary coefficients and standard errors. The excess values of adiabatic compressibility and free volume are negative for all the binary mixtures. The results are interpreted in terms of molecular interactions present in the mixtures.]]>Saravanakumar, K., R. Baskaran and T.R. Kubendran,2010Singh, S., V.K. Rattan, S. Kapoor, R. Kumar and A.
