Densities, viscosities, and refractive indices for the binary mixtures of 1.2-dichloroethane with chlorobenzene and bromobenzene have been determined from (298.15 to 313.15) K over the entire range of concentration at atmospheric pressure. Excess molar volumes have been calculated from the experimental data and lined to a Redlich-Kister polynomial function. The ability of the Prigogine-Flory-Patterson (PFP) theory to predict V(m)(E) at 303.15 K has been tested.
