The constant-volume method is used to determine the solubility of CO₂ in dimethyl carbonate (DMC) under the pressure of 6 MPa and the temperature variations from (280.7 to 327.66) K in this paper. It is found by contrast that DMC has greater ability to dissolve CO₂ than propylene carbonate and methanol at the same temperature. Furthermore, the solubility of CO₂ in DMC at room temperature 298.47 K is close to that of methanol at 263.15 K. Therefore, DMC is expected to become an effective and low-cost absorbent for precombustion CO₂ capture.
