| Abstract
| - A recirculation apparatus in which the vapor phase was forced through the liquid was used to measureisothermal 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 equilibrium wasmeasured with a gas chromatograph that was calibrated with gravimetrically prepared mixtures. Thesystem shows a small deviation from Raoult's law. The data were reduced with the Carnahan−Starling−De Santis (CSD) equation of state. The deviations observed in vapor composition suggest a relativelygood consistency of the experimental findings and the model used for their reduction.
