摘要：
A mixture of 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide (BMIM] [NTf2]) and monoethanolamine (MEA) were added into a dipolar aprotic solvent, sulfolane to form a nonaqueous physical-chemical absorbent for CO2 absorption. The CO2 solubility achieved highest value of 2.861 mol/kg in mixture of 30 wt % MEA + 70 wt % sulfolane (0B30M) at 303.15 K and 2004 kPa. Comprehensive data on effect of temperature, pressure, and composition on the multicomponent were measured and correlated with maximum average absolute relative deviation of 4.89%. Formation of biphasic layer was observed and it was analyzed using nuclear magnetic resonance (NMR).
