Outline of Final Research Achievements

Belousov-Zhabotinsky (BZ) reaction is the chemical oscillation reaction in which the redox state of the metal catalyst such as Ru(bpy)3 can periodically change during the oxidation reaction from an organic reductant such as malonic acid to a bromomalonic acid with an oxidizing agent such as sodium bromate. Recently, we have found that the oscillation behavior of the BZ reaction in certain hydrated protic ionic liquids (PILs) became stable, long-lasting, and short period, although, the reaction condition of the BZ reaction in PILs was mild compared to conventional aqueous solution containing strong acid such as nitric acid or sulfuric acid. In this study, we elucidated the effect of the cation structure on the chemical oscillation reaction by systematic study on the chemical structure of the PILs.
