Outline of Final Research Achievements

Metals contained in wastes called urban mines are drawing attention as they aim for effective use of resources. In this application, we conducted research on the construction of technology for separating and collecting these.
The bisbetadiketone ligand synthesized in this application has a higher extractability than the ordinary betadiketone ligand, and a synergic extraction system with high selectivity was clarified.In addition, the availability was clarified from the viewpoint of complex formation reaction and separation chemistry by equilibrium analysis by solvent extraction method.

Academic Significance and Societal Importance of the Research Achievements

エチルエステルとアセトフェノン誘導体と還元剤を用いてアルキル鎖または芳香環の両端にベータ-ジケトンが結合した、置換基または剛直性の異なる負二価の四座配位子を合成した。この配位子の錯体生成反応と抽出機構に関する詳細な研究を行った。この配位子は新規な抽出試薬で、本申請では、希土類金属イオンをもちいてこれらの配位子の抽出能と選択性の向上効果を明らかにした。
本申請で合成したビスベータジケトン配位子は、通常のベータジケトン配位子と比較して、高い抽出能を示すと共に、選択性が高い協同抽出系を明らかにした。また、溶媒抽出法による平衡分析により、錯体形成反応と分離化学の観点からその有用性を明らかにした。
