摘要：

The solubility of carbon dioxide in three bis(trifluoromethylsulfonyl)imide-based ionic liquids: N-methyl-n-pentYlpyrrolidinium bis(trifluoromethylsulfonyl)imide ([p(5)mpyrr][Tf2N]), 1-butyl-2,3-dimethylimidazolium bis(trifluoromethyl sulfonyl)imide abmmiml[Tf2N]), and tributylmethylphosphonium bis(trifluoromethyl sulfonyl)imide ([P-4441][Tf2N]) was measured at 298.15, 313.15, and 343.15K and pressures up to about 1.9 MPa. The data were well correlated with the Soave-Redlich-Kwong equation of state (SRK-EoS). Henry's law constants for CO2 in the three ILs ([P(5)mpyrr][Tf2N], [bmmim][Tf2N], and [P-4441][Tf2N]) at 298.15 K were 3.1, 3.5, and 3.3 MPa, respectively. (C) 2014 Elsevier B.V.
