Thermodynamic study of binary mixtures of propilophenone+2-propanol, 2-butanol, 2-pentanol, or 2-hexanol at temperatures of 293.15 to 323.15 K: Modeling by Prigogine-Flory-Patterson theory

In the present work, the density and viscosity of binary mixtures of propiophenone (PP) + 2-propanol, PP + 2-butanol, PP + 2-pentanol, or PP + 2-hehanol were measured over all composition range and in the temperature range of 293.15 to 323.15 K at ambient pressure (0.1 MPa). Using the experimental data of density and viscosity, the excess molar volume and viscosity deviation were calculated and correlated by applying the Redlich-Kister equation. The results show that the excess molar volume of all mixtures is negative over the entire composition range at all temperatures and become more negative with increas-ing temperature. Also, the viscosity deviation of all mixtures is negative over the whole composition range at all temperatures and become less negative with increasing temperature. The excess molar vol-umes of mixtures were correlated by using Prigogine-Flory-Patterson (PFP) theory and the agreement between the calculated values with experimental data is good.
