摘要：Isobaric vapour-liquid equilibrium (VLE) data for the binary systems of ethyl iodide with ethanol, propionic acid and ethyl propionate at 101.3 kPa were measured in an Ellis equilibrium still, and the thermodynamic consistency of the experimental data was checked by the Herington area method and Van Ness method. The non-random two-liquid (NRTL), universal quasichemical (UNIQUAC), and Wilson models were applied to correlate the measured VLE data. All three models represent the experimental values quite well. The system (ethyl iodide + ethanol) presents a minimum azeotropic boiling point at 101.3 kPa, in which the azeotropic temperature and composition are 336.08 K and 63.445 mol% (ethyl iodide). The azeotropic behavior was not found in the other two systems. (C) 2018 Elsevier Ltd.
