Method for preparing carbonyl compound by catalytic oxidation of oxime

The invention discloses a method for preparing carbonyl compound by catalyzing and oxidizing oxime. The method comprises the following steps: using oxime compound as a raw material, dissolving the oxime compound in an organic solvent, using metalloporphyrin compound as a catalyst and oxygen as an oxidant, controlling the reaction temperature at 30 to 100 DEG C, and constantly reacting for 1 to 12hours to obtain the carbonyl compound. The method has the advantages of moderate reaction condition, little dosage of the catalyst, good catalytic effect, simple technique, good product yield and selectivity, and the like.
