摘要：

Kinetics and mechanism of iridium (III) catalysed oxidation of Glycols by cerium (IV) in aqueous sulphuric acid medium have been investigated at different temperatures [Glycols] >> Ce (IV) >> (IR) (10(-5) mol/dm(3)) in 1 mol dm(-3) sulphuric acid medium. The reactions are found to be the first order with respect to Ce (IV) ion and observed first order rate constant. From the [HSO4] dependence, Ce (IV) has been found kinetically active the proposed mechanism involves a pre-equilibrium interaction between the catalyst and substrate. The process is acid catalysed. Activation parameters have been determined to investigate the effect of temperature; and probable rate law and mechanism has been proposed.
