| Outline of Final Research Achievements |
In this work, an original entropy-based solubility Parameter (eSP) was developped for high-pressure extraction and separation processes with supercritical carbon dioxide. As a result, predictive Dimensionless Solubility (pDS) model was also originally developped for solid-solute solubility estimation in supercritical carbon dioxide. Counter-current extractions was modeled with a originally-developped equilibrium stage model based on the high-pressure vapor-liquid equilibrium data. We succeeded in theoretical and quantitative analyses for extraction and separation processes with supercritical carbon dioxide.

| Academic Significance and Societal Importance of the Research Achievements |
超臨界・亜臨界流体など高圧状態でも定量化できるエントロピー型溶解度パラメータ（eSP）は，抽出分離実験の理論予測に役立てることができる．また，開発した向流接触型亜臨界溶媒分離装置は，スケールアップも可能であり，今後の社会実装に期待される．なお，これらの業績が評価され，平成30年度には，文部科学大臣表彰（若手科学者賞）を受賞することができた．
