研究概要

医薬品、食品などで多用されている結晶性物質を生産するための手法、すなわち「晶析操作」に関する研究開発を行っています。結晶性粒子群の品質として、粒径分布、純度、結晶多形、結晶形態などが挙げられますが、それらの品質を高度に制御しながら効率よく製造する技術を研究しています。具体的な研究例は次の通りです。
(1)非溶媒添加晶析(貧溶媒添加晶析)
・非溶媒添加晶析での医薬品結晶の多形等高度品質制御
・オイルアウトする溶液からの結晶成長現象
(2)機能性結晶粒子群の創製
・気泡/溶液界面を晶析場とした有機微結晶粒子群の創成
・結晶粒子群の形態をダイナミックに制御するための添加物効果
・ミリ-マイクロ流路と変調操作を組み合わせた微結晶粒子群創成
(3)回分晶析(冷却晶析、反応晶析)
・変調操作を利用した回分晶析の結晶粒子群品質制御とそのモデル作成
・有機塩形成の反応晶析での過飽和操作設計
(4)持続型社会実現のための晶析技術開発
・海水溶存資源回収と有効利用のための晶析操作法
