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