Description
Summary:Densities and vapor-liquid equilibria were determined for tetrahydrofuran with propan-1-ol and propan-2-ol systems at 298.15 K. From the experimental results, excess molar volumes and excess Gibbs free energies were calculated. Information could be obtained from the possible interaction between both chemical species in the two systems. The Prigogine-Flory-Patterson method was applied to calculate excess molar volumes. Liquid activity coefficients were calculated and correlated with different expressions existing in the literature. Keywords: excess molar volumes, vapor-liquid equilibria, activity coefficients, excess Gibbs free energies, tetrahydrofuran, propan-1-ol, propan-2-ol.
