Abstract
Thermal conductivity of liquid 1,1,1,2,3,3-hexafluoropropane (R-236ea) has been measured by the method of high-frequency thermal waves in the temperature range from 264 to 354 K and pressures of up to 31.7 bar. The estimated measurement errors do not exceed 1.5 %. It was shown that molecular thermal conductivity of R-236ea linearly increases with the pressure rise, while the temperature rise has an opposite effect. New predictive method for liquid thermal conductivity of fluorinated derivatives of propane is suggested.
