Development of chemical processes without organic solvents
Possible reduction of environmental load caused by chemical reactions through aqueous synthesis, etc.

Research Overview
It has long been accepted that chemical processes use organic solvents. However, in this project, a technique by which aqueous synthesis is performed without the use of organic solvents has been developed. Additionally, a technique to immobilize metallic catalysts that are highly active, easily collected and reused has been developed. These techniques have high potential as chemical processes with a lower environmental burden and superior economic efficiency.

Impact of Research Achievements
Efficient synthesis of drugs, fertilizers and aromatics, and cost reduction of organic chemical materials
■ Effective use of resources such as rare metals
■ Reduction of environmental burdens through reduced emissions of organic solvents and metals.
■ Proposition and demonstration of environmentally friendly chemical industry
■ Collaborative project with companies is ongoing.
