Provided is a method for easily and efficiently recovering an oxoacid catalyst without deterioration in reaction product yield and catalytic activity, where the oxoacid catalyst has been used in a reaction for oxidizing an organic compound with hydrogen peroxide, also provided is a method for producing an oxide in which an organic compound is oxidized with hydrogen peroxide using the oxoacid catalyst recovered by the method, to yield the corresponding oxide.
A method according to the present invention recovers an oxoacid catalyst used in a reaction for oxidizing an organic compound with hydrogen peroxide in an aqueous/organic solvent two-phase system. The method includes Step 1 in which the pH in the reaction system is adjusted to 5.0 or higher so as to transfer the oxoacid catalyst to the aqueous phase, and the organic phase is removed.
