Outline of Final Research Achievements

This study challenged to find possibilities of new separation process using specific adsorption properties of ZIFs (zeolitic Imidazolate Frameworks) and controlling adsorption velocity. Although aromatics and oxygenated cyclic hydrocarbons adsorbed on ZIF-8 well, saturated cyclic hydrocarbons hardly adsorbed on ZIF-8. By decreasing particle size of ZIF-8, adsorption equilibrium time for 1,4-dioxane adsorption on ZIF-8 is confirmed to be shorter. 1,4-dioxane adsorption using ZIF-8 was carried out in water and in organic solution. Adsorption isotherm of 1,4-dixone on ZIF-8 in low equilibrium concentration region depended on the solvent. Based on the information obtained in this study, possibility of continuous adsorptive separation system of cyclic organics using phase transfer of ZIFs between organic phase and water phase.

Academic Significance and Societal Importance of the Research Achievements

不飽和度,ヘテロ原子数の異なる環状炭化水素の吸着剤としてのZIFsの活用に関する研究例は少ない.本研究では環状炭化水素の不飽和度,ヘテロ原子数により選択的な分離の可能性を示すとともに,溶媒種により吸着特性が変化することを明らかにした.本研究で検討している分離プロセスが実用化できればエネルギー消費の少ない温和な条件で定常的に選択的な分離操作が可能となると期待される.
