Abstract

Bubble point pressures of three binary mixtures at two compositions each have been measured utilizing a static method. The mixtures studied were: difluoromethane + 2,3,3,3 tetrafluoroprop-1-ene (R-32/1234yf), difluoromethane + (E)-1,3,3,3-tetrafluoroprop-1-ene (R-32/1234ze(E)) and 1,1-difluororethene + 2,3,3,3 tetrafluoroprop-1-ene (R-1132a/1234yf). For all the mixtures the minimum temperature measured was 270 K. The maximum temperatures measured for the R-32/1234ze(E), R-32/1234yf and R-1132a/1234yf mixtures were 360 K, 345 K and 325 K respectively. A total of 100 bubble point pressures are reported and compared to available literature data relative to the REFPROP database1. Additionally, the bubble point pressures obtained in this study are modeled using the perturbed-chain statistical associating fluid theory (PC-SAFT) equation of state. The PC-SAFT model parameters are reported as well as deviations of this work and literature data from the model.
