Abstract
The present study concerns phase equilibria measurements involving oxygenated components (furan and furfural) and potential solvents of extraction (n-hexane, ethanol and n-octanol) using an ebulliometer at atmospheric pressure. New liquid-liquid equilibrium data concerning the ternary system furan + furfural + n-hexane are also presented. The experimental technique used for the liquid-liquid equilibrium measurements is based on the static analytic method. The two liquid phases are sampled using a syringe and analyzed using gas chromatograph. Two thermodynamic approaches are considered for the data treatment: the first considers a dissymmetric approach using the NRTL activity coefficient model, and the second considers a group contribution model based on the PC-SAFT EoS (GC-PPC SAFT). The experimentally measured data were successfully correlated with the models proposed.
