Abstract: This work presents a study to apply ionic liquids as potential industrial solvents for carbon dioxide capture. In order to obtain effective ionic liquid solvents,3-(2-amino-ethyl)-1-methyl-1H-imidazol-3-ium-bis((triflouromethyl)sulfonyl)amide(I),3-(3-amino-propyl)-1-methyl-1H-imidazol-3-ium-bis((triflouromethyl) sulfonyl)amide (II) ,3-(2-amino-ethyl)-1-methyl-1H-imidazol-3iumtetrafluoroborate(III), and 3-(3-aminopropyl)-1-methyl-1H-imidazol-3-iumtetrafluoroborate(IV) were synthesized and characterized by using elemental analysis, IR, 1H-NMR, and Mass spectroscopy. The solutions of (I-IV)were prepared by dissolving with methanol. The absorption of CO2 was obtained by gas chromatography. The results show that the synthesized ionic liquids have high efficiency for capture of CO2 from natural gas.
