PURPOSE:To obtain tolualdehyde or methyl benzyl nitrate at a high conversion by oxidizing electrolytically xylene in an acetonitrile solvent in the presence or absence of oxygen by using a platinum anode and an electrolyte of metallic nitrate. CONSTITUTION:Xylene is electrolytically oxidized in an acetonitrile solvent by using platinum for an anode and metallic nitrate as an electrolyte to be dissolved in an electrolytic soln. while supplying oxygen to the acetonitrile solvent, by which tolualdehyde is obtd. Methyl benzyl nitrate is obtd. by oxidizing electrolytically xylene in the acetonitrile solvent in nitrogen atmosphere or non- supply of oxygen in the above-mentioned method. The temp. of the electrolytic bath in the synthesis of said tolualdehyde is preferably as low as about <=45 deg.C and the concn. of the metallic nitrate in the electrolyte is preferably about >=0.1mol/l. The temp. of the electrolytic bath in the production of the methyl benzyl nitrate is preferably an ordinary temp. or relatively high temp. and the moisture in the reaction vessel is preferably about <=5vol%.
