LIQUID PHASE OXIDATION REACTION BY USING TUNGSTEN SPECIES

摘要

PROBLEM TO BE SOLVED: To provide a method for improving/maintaining catalytic activity performance and also suppressing the dissolution of tungsten species into a reaction solution so as to suppress the reduction of the catalyst activity and be able to reutilizing the catalyst in performing a liquid phase oxidation reaction by using the catalyst consisting of the tungsten species as an essential component.

SOLUTION: This liquid phase oxidation reaction by using the catalyst consisting of the tungsten species as the essential component is provided by loading the tungsten species on a porous carrier and incorporating a third element excluding the porous material-constituting components and tungsten element in the catalyst.
