Production of phenols from a cyclic sugar alcohol in high-temperature water over a charcoal-supported platinum catalyst.

ABSTRACT: Biomass is a useful carbon-neutral feedstock for the production of various chemicals. The conversion of cyclic sugar alcohols to aromatic compounds can be expected to promote greater use of biomass resources. Here, we examined the conversion of myo-inositol, a cyclic sugar alcohol present in high amounts in rice bran, to aromatic compounds over supported metal catalysts in high-temperature water. We confirmed that myo-inositol could be converted into phenolic compounds such as phenol and catechol over several charcoal-supported metal catalysts in high-temperature water at 250 °C; the yield of phenolic compounds decreased in the order of Pt/C (42%) > Rh/C (24%) > Ru/C (12%) > Pd/C (0.8%) > no catalyst (0%). To understand more about the reaction pathway, the conversion was repe
