Résumé :	Group contribution methods are used to predict the critical temperatures, critical pressures, critical densities, acentric factors, and ideal gas specific heats at constant pressure for eight fluorinated olefins, namely: R-1225ye(E), R-1225ye(Z), R-1225zc, R-1234ye(E), R-1234yf, R-1234ze(E), R-1234ze(Z), and R-1243zf. For the same eight refrigerants, the Peng–Robinson equation of state is used to predict thermodynamic properties, which are presented in pressure-enthalpy and temperature-entropy state diagrams. To provide the reader with some sense of the predictive capability of the methodology, property predictions for R-134a are compared to known data. Property predictions for R-1234yf are compared, where possible, to the open literature.
