Liquid phase oxygenation reaction using tungsten species

摘要

A catalyst comprising tungsten species, which is supported on a porous support as essential component, is used and liquid phase oxidation reaction is performed. The catalyst comprises a third element, which coexists with the tungsten element other than the component elements of porous support. An independent claim is also included for the prevention of leaching of tungsten species which involves carrying out liquid phase oxidation reaction using tungsten species.
