Investigation of the thermodynamic properties of (Furfuryl Alcohol + Toluene), (Furfuryl Alcohol + Ethanol), or + (Furfural + Toluene) binary mixtures at several temperatures

Abstract : Vapor-liquid equilibrium (VLE) data are essential for the design of separation processes and equipment as well as for the extension of thermodynamic models. The present paper is part of a research program concerning the investigation of the thermodynamic properties of biofuels containing systems. The vapor-liquid equilibria data for the (furfuryl alcohol + toluene), (furfuryl + ethanol), or (furfuryl + toluene) binary mixtures measured using a static device at temperatures between 263 and 363 K are reported. The data were correlated with the Antoine equation. From these data excess Gibbs functions (GE) were calculated for several constant temperatures and fitted to a fourth-order Redlich-Kister equation using the Barker's method. The three binary systems exhibit positive deviations in GE for all investigated temperatures over the whole composition range. The NRTL, UNIQUAC and UNIFAC models have also been used and good results were obtained in the prediction of the total pressure and thermodynamic excess properties.
