ABSTRACT
Vapor-liquid equilibrium data (p, T, x, F) for the carbon dioxide + ethyl propanoate (EP) and carbon dioxide + ethyl acetate (EA) systems were measured from 313 K to 393 K and in the pressure range from 2.96 MPa to 11.97 MPa. The measurements were carried out in a cylindrical autoclave with a moveable piston and an observation window. The results show that the solubilities of CO2 in ethyl propanoate and ethyl acetate strongly increase with pressure, but the concentration of ethyl propanoate or ethyl acetate in the gas phase only slightly increases. The experimental data were correlated using the Peng-Robinson equation of state (EOS) with the two-parameter van der Waals mixing rule.
