Description

General description

1-Butyl-3-methylimidazolium acetate is a room temperature ionic liquid.[1] It is reported to irreversibly adsorb gaseous CO₂, therefore can be a useful means for the separation of greenhouse gas.[2] 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).[1]

Application

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.[1]
