文摘

Alkanolamine-based dual functional ionic liquids were synthesized for CO2 capture. The CO2-absorption molar ratio of [Na(MDEA)2][Pyra] is as high as 0.75 at T = 353.2 K. CO2 can react with a quasi-aza-crown ether cation and pyrazolide anion simultaneously. The ILs could be used to capture CO2 at relatively high temperature.
