ABSTRACT

Phase equilibrium data for the binary systems {carbon dioxide (CO2) + dimethyl carbonate (DMC)} and {carbon dioxide (CO2) + diethyl carbonate (DEC)} were measured at temperatures of 273 K, 283 K and 293 K in the pressure range of 0.5 MPa to 4.0 MPa. The measurements were carried out in a cylindrical autoclave with a moveable piston and an observation window. The experimental data were correlated with the Peng Robison (PR) equation of state (EOS) and the Peng Robinson Stryjek Vera (PRSV) equation of state with van der Waals-1 or Panagiotopoulos Reid mixing rules. The correlations produced reasonable values for the interaction parameters. The comparisons between calculation results and experimental data indicate that the PRSV equation of state coupled with the Panagiotopoulos Reid mixing rule produced the better correlated results.
