Abstract: PURPOSE: A carbon dioxide absorbent using imidazolium ionic liquid compounds containing fluorinated olefin is provided to ensure thermal stability and excellent carbon dioxide absorption ability. CONSTITUTION: An imidazolium ionic liquid compound containing fluorinated olefin with carbon dioxide absorption ability is denoted by chemical formula 1. A method for preparing the imidazolium ionic liquid compound comprises: a step of reacting Brensted acid with 1,2-dialkylimidazole of chemical formula 2 under the presence of an organic solvent to form a salt; and a step of adding fluorinated olefin gas to the salt. Brensted acid is HCl, CF_3CO_2H, CH_3CO_2H, HBF_4, (CF_3SO_2)_2NH, or CF_3SO_3H. The organic solvent is tetrahydrofuran.
