The vapor–liquid equilibrium (VLE) for the binary systems 1,1,2,3,3,3-hexafluoro-1-propene (R1216) + 2,3,3,3-tetrafluoroprop-1-ene (R1234yf) and 1,1,2,3,3,3-hexafluoro-1-propene (R1216) + trans-1,3,3,3-tetrafluoropropene (R1234ze(E)) have been investigated from 283.43 to 323.32 K and 283.28 to 323.16 K, respectively. The experimental apparatus was a recirculation system with a liquid phase pump to accelerate the VLE process. The Peng–Robinson equation of state combined with Mathias–Copeman alpha function, modified Huron–Vidal mixing rule, and nonrandom two-liquid activity coefficient model was employed to correlate the VLE data. The correlated results showed good agreement with the experimental results for the two mixtures. The average absolute relative deviation of pressure (AARDp) and average absolute deviation of vapor composition (AADy) were 0.32% and 0.003 for R1216 + R1234yf, and 0.21% and 0.004 for R1216 + R1234ze(E), respectively. The experimental and correlated results showed that there was a positive azeotrope for the system R1216 + R1234yf over all tested temperatures.
