Abstract
A recirculation apparatus in which the vapor phase was forced through the l iquid was used to measure isothermal vapor-liquid equilibria (VLE) for the binary system 1,1,1-trifluroethane (R143a) + 1,1,1,3,3,3-hexafluoropropane (R236fa) at 283.11, 298.16, and 313.21 K. The phase composition at equilibr ium was measured with a gas chromatograph that was calibrated with gravimet rically prepared mixtures. The system shows a small deviation from Raoult's law. The data were reduced with the Carnahan-Starling-De Santis (CSD) equa tion of state. The deviations observed in vapor composition suggest a relat ively good consistency of the experimental findings and the model used for their reduction.
