Abstract

OH radicals, produced in aqueous acid media by the electrogenerated system Fe(II)/H2O2, promote the oxidation of polymethylated benzenes. Under our experimental conditions only one -CH3 group was oxidized to -CHO. A reduction of aldehyde to alcohol by.OOH radicals was shown to occur when H2O2 was produced in excess over Fe(II). In hydrochloric acid or in perchloric acid with Cl− ions added, a remarkable increase of the yields was observed. The results are discussed on the basis of the kinetic parameters of the reactions involved in the process.
