Cobalt bromide catalysis of the oxidation of organic compounds. I. Mechanism of the reduction of trivalent cobalt ions
This paper studies the kinetics of the reduction of cobalt (III) acetate formed in the oxidation of alkyl aromatic hydrocarbons with a cobalt bromide catalyst spectrophotometrically. It was established that at low bromide concentrations, the particle directly responsible for reduction is cobalt (II) monobromide. The rate constant and activation energy of the reaction were determined and it was established that cobalt monobromide is regenerated during the oxidation process. The existence of a cycle of bromide reduction, as a result of which Co(III) is reduced according to a catalytic reaction with the hydrocarbon, forming an alkyl radical R, which continues the chain, while cobalt(II) monobromide serves as a catalyst of the reduction reaction, was demonstrated.
