摘要：

Densities (rho) and ultrasonic speeds (u) of the binary mixtures 2-chlorotoluene or 4-chlorotoluene or 1,3-dichlorobenzene (1) + 1,4-dioxane (2) were measured at temperature 298.15-318.15 K and atmospheric pressure. Using these measurements, excess volume (V-m(E)) and deviation in ultrasonic speed (u(E)) were calculated. Excess isentropic compressibility (kappa(E)(s)) was calculated using rho and u values. The V-m(E) values have been interpreted by Prigogine-Flory-Patterson (PFP) theory also. The V-m(E) obtained using PFP theory agree well with experimental values. The u values were also calculated using various empirical relations. The available volume (V-a) and intermolecular free length (L-f(E)) were calculated using experimental u values by employing Jacobson free length theory.
