| Outline of Final Research Achievements |
It is considered that CO2 is one of the causative agents for the global Warming Hence, It is required to reduce atmospheric CO2. Although CO2 absorption processes using aqueous solutions, it is necessary to develop more efficient process. Ionic liquids, which consist of only ions and have a melting point around ambient temperature, show good CO2 solubility so that their applications to the next generation CO2 absorption process is eagerly expected. For the acetate based ionic liquid, the solution mechanism that CO2 forms a new compound to dissolve in them is proposed. However, its structure in solution is still unknown. Knowledge of such a solution mechanism and/or structure of newly formed CO2 compound in solution leads to develop more efficient CO2 absorption liquids/process. In this study, structure of newly formed CO2 compound in an acetate based ionic liquid was revealed by means of combination of spectroscopic/scattering experiments and theoretical calculations.
