Gamma-valerolactone (GVL) has been proposed as a biomass-based platform molecule. However, its vapor-liquid equilibrium has not been exhaustively studied yet. Antoine constants of GVL were determined and vapor-liquid equilibrium (VLE) data for water(1)-GVL(2) binary system were measured at atmospheric and reduced (50.66 and 10.1 kPa) pressures. The thermodynamic consistency was investigated by applying Herrington's area test. It was established that no azeotropic mixture was formed for the water-GVL system in the full concentration range. Data were regressed using ChemCAD software to generate binary interaction parameters for Wilson, NRTL, and UNIQUAC activity coefficient models. Good agreements between calculated and experimental VLE data were obtained.
