Influence of Temperature on the Densities of Binary Mixtures of Benzene with Methanol and Ethanol

The densities of the binary mixtures benzene + methanol and benzene + ethanol have been measured at 288.15, 293.15, 298.15, 303.15, 308.15 K and atmospheric pressure over the whole composition range. The correlation of the density of these solutions with temperature and composition was performed with Emmerling et al. and Jouyban-Acree models. Values of excess molar volume were calculated from experimental measurements of density and a Redlich-Kister equation type was used to correlate this excess property. Knowledge of these mixing properties has relevance in both theoretical and applied areas of research because such results are useful in design and simulation processes for petrochemical industry.
