(Vapor + liquid) equilibrium (VLE) data for a binary system of {1,1-difluoroethene (R152a) + trans-1,3,3,3-tetrafluoropropene (R1234ze (E))} were measured by a static-analytic method at temperatures ranging from 258.150 to 288.150 K. All data were correlated by the Peng-Robinson equation of state (PR EoS) with the Huron-Vidal (HV) mixing rule involving the nonrandom two-liquid (NRTL) activity coefficient model. The correlated results show good agreement with the experimental data at each temperature point. The maximum average absolute relative deviation of pressure is 0.17%, while the maximum average absolute deviation of vapor phase mole fraction is 0.0020. Obviously the binary mixture is a zeotropic system at the measured temperature range.
