PVTx measurements for the R125 + CO2 system by the Burnett method

Fluid Phase Equilibria, 2002
Abstract The PVTx behaviour for the carbon dioxide (CO2)+pentafluoroethane (R125) system was measured by the Burnett method within the range 323–363 K and at pressures from 10 to 5000 kPa. The apparatus was calibrated by means of helium and its performance was checked by measurements of PVT for the mixture components.

PVTx properties in the gas phase for binary HFC-161/125 system

Fluid Phase Equilibria, 2006
Abstract The gaseous PVTx properties of ethyl fluoride (HFC-161) + pentafluoroethane (HFC-125) mixtures were measured at temperatures from 305.154 to 393.228 K and corresponding pressures from 1032.5 to 5416.5 kPa using the isochoric method. The uncertainties in the present measurements were estimated to be ±1.5 kPa for pressure and ±6 mK for ...

PVTx Measurements for a H2O + Methanol Mixture in the Subcritical and Supercritical Regions

International Journal of Thermophysics, 2004
PVTx relationships for a H2O + CH3OH mixture (0.36 mole fraction of methanol) were measured in a range of temperatures from 373 to 673 K and pressures between 0.042 and 90.9 MPa. The density ranged from 37.76 to 559.03 kg · m−3. Measurements were made with a constant-volume piezometer surrounded by a precision thermostat.
