Excess molar volume, E m V , and excess partial molar volume, E i V , of binary liquid mixtures of acetic acid (1) + mxylene (2), acetic acid (1) + o-xylene (2), acetic acid + p-xylene, trichloroethylene (1) + m-xylene (2), , trichloroethylene (1) + o-xylene (2) and , trichloroethylene (1) + p-xylene (2) have been investigated from the density, r , measurements over the entire range of composition at temperatures (293.15, 298.15, and 303.15) K and at P = 81.5 kPa. The dynamic viscosity, h , and the refractive indices, D n , of the binary mixtures at temperature 303.15 K were measured. The measured systems exhibited negative values of E m V and become more negative with increasing temperature. The excess molar volumes, dynamic viscosity and refractive indices deviations were correlated with the Redlich-Kister.
