High pressure vapor-liquid equilibrium data for the carbon dioxide+dimethyl carbonate (DMC) binary system were measured at four temperatures in the 333.0 to 393.0 K range and under pressures ranging from 3.98 to 13.75 MPa. The experimental data were correlated with the Peng-Robison (PR) cubic equation of state and the van der Waals-1 mixing rule. The binary interaction parameters were also obtained. The agreement between experimental results and calculations was good.
