摘要
Experimental densities, ρ, and refractive indices, n D for binary liquid mixtures of benzene with triethylamine (TEA) and tributylamine (TBA) have been measured as a function of composition in the temperature range from 278.15 to 318.15 K. The excess molar volume, V E , and its temperature dependence, dV E /dT for the binary mixtures were calculated using the experimental data. The values of V E for the mixtures were also estimated by using the Flory statistical theory and refractive index.
