Article Description

The density (ρ), speed of sound (u), and refractive indices (n) data at atmospheric pressure for benzene + n-heptane + n-octane mixtures from 298.15 to 318.15 K have been measured. The data were further used to derive excess molar volume (V ) and deviation in u (Δu) and n (Δn). The V values for the ternary mixtures were positive and predicted from the constituent binary data using various fitting equations, geometrical solution models, and the Prigogine−Flory−Patterson theory. The u data at 298.15 K were analyzed by Schaaff's collision factor theory and Nomoto correlations. Using the Jacobson free length theory, L and V were also calculated. The n data for these mixtures were also predicted from the pure component data.
