Outline of Final Research Achievements

Hot compressed water shows characteristic solvent properties depending on temperature and pressure. In this research, effects of hot compressed water on reactivity and stability of solid acid catalysts were quantitatively elucidated by experimental methods and kinetic analyses. By using our findings in order to control the solid acid catalysis, it is expected to improve products yield and catalysts life for dehydration reactions and other acid catalyzed reactions.
