ABSTRACT
The density of gaseous and liquid 1,1,1,2,3,3-hexafluoropropane (HFC-236ea) and speed of sound in liquid HFC-236ea have been studied by an -attenuation technique, an ultrasonic interferometer, and an isochoric piezometer method over the temperature range of 263 to 423 K at pressures up to 4.05 MPa. The purity of the samples used throughout the measurements is 99.68 mol%. The pressures of the saturated vapor were measured over the same temperature range. The experimental uncertainties of the temperature, pressure, density, and speed-of-sound measurements were estimated to be within 20 mK, 1.5 kPa, (0.05-0.30)%, and (0.05-0.10)%, respectively
