High-pressure (vapour plus liquid) equilibria in (carbon dioxide plus acetone or 2-propanol) at temperatures from 293 K to 333 K

High-pressure (vapour + liquid) equilibria in (carbon dioxide + acetone, or 2-propanol) at temperatures from 293 K to 333 K and pressures between 1.1 MPa and 8.1 MPa are reported. The new experimental results an in good agree ment with selected literature data. The new data are correlated by two equa tions of state: the Peng-Robinson equation of state as modified by Melhem e t nl. and the generalized Bender equation of state. Both equations give a g ood description of the pressure above such liquid mixtures. The correlation s give good results for the vapour phase composition of 2-propanol, whereas the calculated vapour phase composition of acetone (for a given temperatur e and a liquid phase composition) is somewhat less than the experimental re sults.
