AN OXIDATION REACTION MIXTURE (E.G. ADIPIC ACID, BENZOIC ACID, BUTENEDIOL) AND AN OXIDATION CATALYST ARE EFFICIENTLY SEPARATED FROM A REACTION MIXTURE WITH THE USE OF AN AQUEOUS SOLVENT (E.G. METHYL BENZOATE, BENZONITRILE) CONTAINING AT LEAST WATER (E.G. WATER) AND A NON-WATER-SOLUBLE SOLVENT SEPARABLE FROM THE AQUEOUS SOLVENT, THE REACTION MIXTURE BEING OBTAINED BY OXIDIZING A SUBSTRATE (E.G. A HYDROCARBON) IN THE PRESENCE OF AN IMIDE COMPOUND SUCH AS N-HYDROXYPHTHALIMIDE SHOWN BY THE FOLLOWING FORMULA (1) AS THE OXIDATION CATALYST,(FORMULA 1) WHEREIN R1 AND R2 REPRESENTS A SUBSTITUENT SUCH AS A HYDROGEN ATOM AND A HALOGEN ATOM; R1 AND R2 MAY TOGETHER FORM A DOUBLE BOND, OR AN AROMATIC OR NONAROMATIC 5- TO 12- MEMBERED RING; X STANDS FOR O OR OH; AND N IS 1 TO 3. NO DECOMPOSITION OF THE OXIDATION CATALYST IS OBSERVED IN THIS SEPARATION PROCESS. |
