Abstract
Isothermal vapor-liquid equilibrium data were measured for the binary mixture of 1,1,1-trifluoroethane (HFC-143a)+propane (HC-290) at six equally spaced temperatures between 268.15 and 318.15 K by using a circulation-type equilibrium apparatus. The phase composition at equilibrium was measured by gas chromatography. The experimental data were compared with the calculated data based on the Carnahan-Starling-De Santis (CSD) equation of state. Good agreement between experimental and calculated data indicates that the CSD equation of state can be used to estimate thermodynamic properties for the mixture of HFC-143a+propane in the range of temperatures between 268.15 and 318.15 K. The binary system of HFC-143a+propane exhibits azeotropes.
