MANGANESE(II) CATALYSED CERIUM(IV) OXIDATION OF MANDELIC ACID IN AQUEOUS SULPHURIC ACID MEDIUM

摘要

The oxidation of mandelic acid by Ce(IV) has been studied in aqueous sulphuric acid medium.A minute amount of 10~(-4) mol dm~(-3) of Mn(II) is sufficient to catalyse the reaction.The active species of catalyst and oxidant are MnOH~(2+) and CeOH~(3+),respectively.Plausible mechanism is proposed and the reaction constants involved have been determined.
