Isothermal vapor-liquid equilibrium for binary mixtures containing furfural and its derivatives
The isothermal vapor-liquid equilibrium (VLE) data were measured for the binary systems of 2-methylfuran+ furfuryl alcohol, isopropyl alcohol + furfuryl alcohol, and furan + furfural at 353.2, 373.2, and 408.2K over entire composition range, including the vapor pressures of five constituent compounds. The experimental results of the investigated binary systems show no azeotrope formation and positive deviations from Raoult's law. The thermodynamic consistency of these new binary VLE data has been confirmed by point, area, and infinite dilution tests. The Wilson-HOC, the NRTL-HOC, and the UNIQUAC-HOC models were used to correlate the VLE data. Comparable results were obtained from these three models. (C) 2014 Elsevier B.V. All rights reserved.
