Measurements and modeling of thermophysical behavior of (C1-C4) alkylbenzoate/(C1-C11) alkan-1-ol mixed solvents

The thermophysical properties of the (C-1-C-11) alkan-1-ol/(C-1-C-4) alkylbenzoate mixed solvents at atmospheric pressure and 298.15 K were studied over the whole composition range. The intermolecular interactions and structural effects were analyzed on the basis of the measured and the derived properties. From the experimental data, the parameters of the extended real associated solution and Prigogine-Flory-Patterson models were used to correlate and interpret the excess molar volumes. The ability of the Soave-Redlich-Kwong and Pen-Robinson equations of state combined with a set of different selected mixing rules for the correlation of the volumetric and viscometric properties was also tested. Valuable information on the behavior and governing factors of the liquid structure of the strongly nonideal solvents studied were inferred from the parameters deduced.
