一般說明
1-Butyl-3-methylimidazolium acetate is a room temperature ionic liquid. It is reported to irreversibly adsorb gaseous CO2, therefore can be a useful means for the separation of greenhouse gas. CO2 has been reported to readily dissolve in 1-butyl-3-methylimidazolium-acetate. It also forms reversible molecular complex with CO2 in the ratio of 1 (CO2) : 2 (1-butyl-3-methylimidazolium-acetate).
應用
1-Butyl-3-methylimidazolium acetate may be used to effectively capture CO2 from post-combustion flue gas. It may be used in the preparation of 1-butyl-3-methylimidazolium-2-carboxylate via carboxylation with CO2.

The formation of 1-butyl-3-methylimidazolium-2-carboxylate in the mixture of CO(2) with 1-butyl-3-methylimidazolium acetate under mild conditions (298 K, 0.1 MPa) has been put in evidence in the liquid phase using Raman and infrared spectroscopy complemented by DFT calculations and NMR ((1)H

Gaseous CO(2) is almost irreversibly absorbed by the room temperature ionic liquid 1-butyl-3-methylimidazolium acetate ([C(4)mim][Ac]) in which it undergoes a chemically irreversible, one electron electrochemical reduction, suggesting a means for the sequestration of the greenhouse gas.
