A novel dual amino-functionalized cation-tethered ionic liquid for CO ₂ capture

• 摘要：

  A novel dual amino-functionalized ionic liquid, 1, 3-di (2′-aminoethyl)-2-methylimidazolium bromide (DAIL), was synthesized and investigated as a potential absorbent for CO₂ capture. CO₂ absorption behavior on pressure, temperature and concentrations of DAIL in aqueous solution were studied, and the absorption mechanism was investigated by spectroscopic methods and DFT calculations. The CO₂ capture capacity of 18.5 wt % and good thermal stability (T_d = 521.6 K) make DAIL a good candidate for industrial applications for CO₂ capture.
