Kinetic Study of the Oxidation of Dimethylsulfoxide by Cerium(IV) in Perchloric Acid Media

Abstract

The kinetics of the oxidation of dimethylsulfoxide by Cerium(IV) in perchloric acid has been investigated spectrophotometrically. The water role has been elucidates by using acidity criteria. A tentative mechanism consistent with the kinetics is discussed, the rate‐determining step being a bimolecular process between ions of positive charge.
