ABSTRACT

Vapor-liquid equilibrium data for the carbon monoxide + dimethyl carbonate, oxygen + dimethyl carbonate, and dimethyl ether + dimethyl carbonate systems were measured at 293 K, 313 K, 353 K, and 373 K and at elevated pressures up to 12.00 MPa. The measurements were carried out in a cylindrical autoclave with a moveable piston and an observation window. The experimental data were correlated using the Peng-Robinson-Stryjek-Vera equation of state (EOS) with the two-parameter van der Waals II mixing rule.
