Isothermal 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.
