ABSTRACT
The phase equilibrium of the binary system carbon dioxide + propene oxide has been determined for carbon dioxide mole fractions from 0.1 to 0.7 and temperatures from (303.2 to 353.2) K. The experimental measurements of bubble points were carried out in an experimental device incorporating a moveable piston and a vision window. A good description of the phase behavior in a wide range of temperatures with the Peng-Robinson equation of state using the one-parameter conventional van der Waals mixing rule has been obtained, on the basis of measured data and literature data for the carbon dioxide + propene oxide system. The binary interaction parameter kij has been optimized to match experimental data at each temperature separately and found to be temperature-dependent, especially at high temperatures.
