- Abstract
- Isothermal vapor-liquid equilibrium data for the binary system of carbon dioxide + dimethyl carbonate (DMC) were measured at 278.15, 283.15, 293.15, 303.15, 313.15, 323.15 and 333.15 K using a circulation-type equilibrium apparatus in which both vapor and liquid phases were recirculated. The equilibrium compositions of vapor and liquid phases and pressures were reported at each temperature. The measured data were correlated with the Peng-Robinson equation of state (PR-EoS) using the Wong-Sandler mixing rules combined with the NRTL excess Gibbs free energy model and the Peng-Robinson equation of state (PR-EoS) using the Universal mixing rule. Calculated results with these equations can be used to estimate the thermodynamic properties of this binary system of CO2 (1) + DMC (2). (c) 2012 Elsevier B.V. All rights reserved.
