The dilute-gas properties of some systems containing CO2

The SSR-MPA potential model is used to correlate and extrapolate the dilutegas properties of some systems containing CO₂. With parameters determined from a consistent set of second virial and Joule-Thomson data, the third virial coefficient of CO₂ as well as the second virial coefficients of various mixtures containing CO₂ can be predicted very well. The Mason-Monchik approximation fails for a complicated molecule such as CO₂, although at least a viscosity prediction of technical accuracy is obtained. If parameters fitted to the CO₂ viscosity are used, excellent predictions can be made for the viscosity of gaseous mixtures containing CO₂.
