• The oxidation of ethyl methyl ketone with manganese(III) sulphate has been studied. The main product of oxidation is acetaldehyde. The reaction is first order with respect to each manganese(III) and the ketone. The rate of oxidation is independent of acidity and is not affected by changes in solvent composition. Addition of manganese(II) also does not affect the rate. The energy of activation, the entropy of activation and free energy of activation at 35°C have values 20.5 kcal/mol, −3.50 e.u. and 21.6 kcal/mol respectively. The rate of enolisation, measured by bromination method, is less than that of oxidation under similar conditions. A mechanism involving an attack directly on the ketone by manganese(III) sulphate-complex has been suggested.
