| Abstract: | 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. |
