Padua Research Archive, l’archivio istituzionale della produzione scientifica dell’Università degli Studi di Padova, ha lo scopo di raccogliere, documentare, conservare e pubblicare, anche ad accesso aperto, i prodotti della ricerca dell’Ateneo. Padua Research Archive utilizza la piattaforma IRIS (Institutional Research Information System) sviluppata da Cineca.
EnglishA recirculation apparatus in which the vapor phase was forced through the liquid was used to measure isothermal vapor - liquid equilibria (VLE) for the binary system 1,1,1-trifluoroethane (R143a) + 1,1,1,3,3,3-hexafluoropropane (R236fa) at 283.11, 298.16, and 313.21 K. The phase composition at equilibrium was measured with a gas chromatograph that was calibrated with gravimetrically prepared mixtures. The system 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 relatively good consistency of the experimental findings and the model used for their reduction.

| Abstract: | A recirculation apparatus in which the vapor phase was forced through the liquid was used to measure isothermal vapor - liquid equilibria (VLE) for the binary system 1,1,1-trifluoroethane (R143a) + 1,1,1,3,3,3-hexafluoropropane (R236fa) at 283.11, 298.16, and 313.21 K. The phase composition at equilibrium was measured with a gas chromatograph that was calibrated with gravimetrically prepared mixtures. The system 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 relatively good consistency of the experimental findings and the model used for their reduction. |
