We present new vapor pressure measurements for 1,1,1,2,3,3-hexafluoropropane (R-236ea) in the temperature range from 300 to 410 K. The measurements were performed with a static technique, and the uncertainties of the measurements were estimated to be within +/-0.6 kPa for pressure and within +/-8 mK for temperature. A Wagner-type vapor pressure correlation was developed to represent the measured vapor pressures, and the critical pressure was determined as (3411.6 +/- 3.0) kPa corresponding to the critical temperature of 412.375 K. The purity of the R-236ea sample used in the present measurements was 99.9 mol %. The effect of the volatile impurity in the sample on the vapor pressure measurements is discussed and corrected.
