The oxygen uptake kinetics in the liquid-phase oxidation of cyclohexanol initiated by cumyl peroxide in the presence of inhibitors (ionol and nitrobenzene) has been investigated (373 K, ortho -dichlorobenzene as the solvent). The relative contributions from the hydroperoxyl and α-hydroxycyclohexylperoxyl radicals to chain propagation has been determined. The rate constants for the reactions of these radicals with the alcohol have been determined.
