文摘

2,3,3,3-Tetrafluoroprop-1-ene (R1234yf) is one of the most promising alternative refrigerants because of its low global warming potential and a vapor pressure similar to 1,1,1,2-tetrafluoroethane (R134a). At present, its measured thermodynamic properties are scarce. Herein, vapor pressure data measurements and corresponding correlations are discussed. In particular, 40 vapor pressure measurements in the temperature range between (245.65 and 343.15) K were obtained, and these results, together with available literature data, were regressed using Wagner-type and extended Antoine-type equations. The normal boiling temperature for R1234yf was calculated to be 243.71 K.
