Vapor−Liquid Equilibria of Binary Carbon Dioxide + Alkyl Carbonate Mixture Systems

Abstract

We measured binary vapor liquid equilibrium data of the carbon dioxide + dimethyl carbonate system and the carbon dioxide + diethyl carbonate system at temperatures from 310 K to 340 K. A circulating type apparatus with on-line gas chromatography was used in this study. The measured data were correlated well by the Peng−Robinson equation of state using van der Waals one fluid mixing rules.

The synthesis of organic carbonates from carbon dioxide

“…Several computational simulations of phase behavior have been reported. [53][54][55] 2.2.7 Reaction mechanism. A typical catalyst for DMC synthesis is Bu 2 Sn(OMe) 2 (1).…”

Prediction of gas solubility in battery formulations

“…(Data [11] are thought to be in error). Until very recently, no data had been available for any binary combinations gas + DMC or DEC, however, two relevant sets of measurements were published lately [12,13]. The database of Henry's constants and VLE data was also extended on MCC data (CO 2 , C 2 H 6 , CH 4 , and N 2 solubilities in EC and PC).…”

“…This problem likely stems from the fact [12,13]. Solid lines are correlations using the PSRK model, dashed lines are predictions using PSRK parameters determined from gas + PC binary data.…”

Vapor-Liquid Equilibrium Data for Carbon Dioxide+Dimethyl Carbonate Binary System

“…[8][9][10] Camy et al 8 reported the equilibrium data for this system at 322.65, 348.15, and 373.55 K in the pressure range of 1.33 to 12.75 MPa. Im et al 9 reported the data at 310.27, 320.36, 330.30, and 340.27 K in the pressure range of 0.827 to 6.136 MPa. Lu et al 10 reported the data at 273, 283, and 293 K in the pressure range of 0.66 to 4.19 MPa.…”
