Isothermal vapor–liquid equilibria of binary systems containing green solvents derived from biomass: (Furfuryl alcohol + toluene), (furfuryl alcohol + ethanol), or (furfural + toluene)
چکیده انگلیسی


• The vapour pressures of the pure furfuryl alcohol, furfural and toluene were measured.
• VLE of furfuryl alcohol + toluene, or + ethanol, and furfural + toluene were also determined.
• The investigated temperatures are 273 (or 283) K to 343 (or 363) K.
• Two systems exhibit positive deviations in GE and one negative deviation.
• The NRTL, UNIQUAC and Modified UNIFAC (Do) models have been used.

The vapor pressures of the pure components: furfuryl alcohol, furfural and toluene along with the binary mixtures (furfuryl alcohol + toluene), (furfuryl alcohol + ethanol), or (furfural + toluene) were measured by means of a static device at temperatures between 273 (or 283) and 343 (or 363) K. The data were correlated with the Antoine equation. From these data excess Gibbs functions were calculated for several constant temperatures and fitted to a fourth-order Redlich–Kister equation using the Barker’s method as two systems exhibit positive deviations in GE and one negative deviations for all investigated temperatures over the whole composition range. The NRTL, UNIQUAC and Modified UNIFAC (Do) models have also been used and good results were obtained in the prediction of the total pressure and thermodynamic excess properties.
