摘要：

Vapor-liquid equilibrium data were measured at 760 mmHg for binary systems of furfural with dichloromethane, 1,2-dichloroethane, trichloroethylene and tetrachloroethylene. A recirculation still was used for this purpose. Liquid-phase activity coefficients were correlated using the Margules, Van Laar, Wilson, NRTL and UNIQUAC models. An analysis of the vapor-liquid equilibrium data presented in this work, along with liquid-liquid equilibrium data for aqueous solutions of furfural, suggest that 1,2-dichoroethane and trichloroethylene are suitable solvents for the liquid-liquid extraction of furfural aqueous solutions.
