[PROBLEMS] To efficiently separate an oxidation reaction product and an oxidation catalyst from an oxidation reaction mixture without decomposing the oxidation catalyst. SOLUTION: An imide compound such as N-hydroxyphthalimide represented by the general formula (1) is used as an oxidation catalyst to oxidize a substrate (such as a hydrocarbon). ) And a water-insoluble solvent (eg, methyl benzoate, benzonitrile) that can be separated from this aqueous solvent, and an oxidation reaction product (eg, adipic acid, benzoic acid, butenediol) and an oxidation catalyst And separate. Embedded image (Wherein, R 1 and R 2 represent a substituent such as a hydrogen atom or a halogen atom, and R 1 and R 2 are bonded to each other to form a double bond, It may form an aromatic or non-aromatic 5- to 12-membered ring. X represents O or OH, and n is 1-3) |
