Abstract: A method of preparing benzaldehyde group or benzyl ketone is provided to oxidize benzylalcohols to benzaldehyde group or benzyl ketone, and to suppress the generation of by-products. A method of preparing benzaldehyde group or benzyl ketone by the oxidation reaction of benzylalcohols or benzyl ketone, comprises a step for obtaining benzaldehyde group or benzyl ketone by the oxidation reaction of benzylalcohols of the chemical formula 1 by using ionic liquid which is ionic salt existing as the liquid state at a temperature of 300°C or less. In the chemical formula 1, R1 is selected from the group consisting of H, alkyl, benzyl, aryl and CN; and R2 is selected from the group consisting of H, alkyl, halogen, benzyl, aryl, cyclic ether, ester and methoxy.
