Abstract

The isobaric specific heat capacity and density of the HFO-1234yf (2,3,3,3-tetrafluoropropene, CH2=CFCF3) in the liquid state have been measured in the temperature range from (310 to 360) K at pressures up to 5 MPa. The uncertainties in temperature, pressure, isobaric specific heat capacity, and density measurements were estimated to be less than 5 mK, 3 kPa, 5 %, and 0.2 %, respectively. A sample with purity of 99.99 mol % or greater was used for the measurement. Experimental values for the isobaric specific heat capacity were correlated as a function of pressure along isotherms, and those for density were correlated as functions of pressure and temperature. In addition, the saturated liquid isobaric specific heat capacity and density were obtained from extrapolation of these correlations to the vapor pressure.
