Highly selective oxidation of methanol to dimethoxymethane over SO42−/V2O5–ZrO2†
Abstract
The sulfated vanadia–zirconia SO42−/V2O5–ZrO2 catalyst, prepared by an impregnation method and calcined at various temperatures, was found to have a high catalytic activity for methanol oxidation to dimethoxymethane in a fixed bed reactor and a batch autoclave using O2 as the oxidant due to the crystalline V2O5 dispersed on the surface as redox active sites, as well as stronger acidic sites.
