Isothermal vapor–liquid equilibrium data for the ethene + 2,2,3-trifluoro-3- (trifluoromethyl)oxirane binary system between 258 and 308 K at pressures up to 4.5 MPa

International audienceIsothermal vapor–liquid equilibrium data (P–x–y) are presented for ethene + 2,2,3-trifluoro-3-(trifluoromethyl)oxirane mixtures at six temperatures in the range 258.38–307.38 K, and pressures up to 4.54 MPa. Experimental P–x–y data were measured using an apparatus based on the " static-analytic " method. The experimental data were correlated with a model composed of the Peng–Robinson equation of state using the Mathias–Copeman alpha function, Wong–Sandler mixing rules and the NRTL local composition model. The thermodynamic model accurately represents the experimental VLE data over the entire temperature range investigated
