Abstract

The kinetics of oxidation of ethylene glycol and 1,3‐butylene glycol by dihydroxydiperiodatoargentate(III) in alkaline medium have been studied by spectrophotometry in the range of 298.2–318.2 K. It is shown that the reaction was first order with respect to each reductant and Ag(III), and k~obs~ increased with an increase of [OH^βˆ’^]. A plausible mechanism of reaction involving a pre‐equilibrium of adduct formation between complex and reductants was proposed, which could be applied to explain all experimental phenomena, and the activation parameters of the rate‐determining step have been also calculated.

with respect to the catalyst concentration is first. The reaction mechanism supposes the formation of a complex between the substrate and the catalyst active form . Subsequently, the complex thus formed slowly decomposes in the rate determining step to give carbonium ions and ruthenium hydride, sinc
