چکیده انگلیسی
Isochoric PVTx measurements have been performed for the binary system of nitrous oxide + CH3F (R41), +CH2F2 (R32), and +CHF3 (R23) using a new experimental set-up. The experiments covered both the two-phase region and the superheated vapor region and were performed within the temperature range 214-358 K and within a pressure range from 270 to 5600 kPa. Data have been collected for not less than four compositions for each system. The vapor-liquid equilibrium data were derived correlating the experimental data by means of the Carnahan-Starling-De Santis equation of state. The studied systems show a positive deviation from the Raoult's law. The results obtained were compared with the Burnett PVTx data. The two methods showed a mutual consistency within an acceptable margin of error. No other experimental PVTx data were found in the literature for these binary systems.
