Outline of Final Research Achievements

In order to develop the ammonia absorption separation technology using ionic liquids, we investigated the ammonia absorption property and mechanism of ionic liquids. In the case of physical absorption of ammonia, the hydrogen bond basicity of and the vacant volume in ionic liquids are important factors. The ionic liquid with the strong basicity and the large volume tends to absorb the larger amount of ammonia. In the case of chemical absorption of ammonia, the ionic liquid with the strong acidic functional group absorbs the larger amount of ammonia. In addition, the intermolecular interaction via hydrogen bonds between molecular ammonia and ammonium is also important to increase the solubility of ammonia. Furthermore, we found that the chemical absorption strongly depends on the acidity of anion species.
