Catalytic Property of Synthetic Imogolite

Abstract

Imogolite is tubular clay mineral with typical chemical composition of (OH) ₃Al₂O₃SiOH. Catalytic property of the synthetic imogolite was examined by the isomerization reaction of α-pinene and the oxidation reaction of cyclohexene using hydroperoxide. The acid property of imogolite was not detected by the isomerization reaction of α-pinene. Results of oxidation reaction of cyclohexene indicated that imogolite has the potential of concentration and plays as a field of reaction to increase collision frequency of reactants. Epoxidation of cyclohexene was observed by reaction using imogolite and acetonitrile as solvent.
