Effect of ketones on the equilibrium between peroxy radicals carrying the chains of cyclohexanol oxidation with molecular oxygen
The influence of methyl phenyl ketone and diphenyl ketone on the kinetics of cyclohexanol oxidation initiated by cumyl peroxide at 373 K was studied. The ratio of the chain propagation rate constant involving the 1-hydroxy-1-phenylethylperoxy radical to the equilibrium constant of radical dissociati...

Zusammenfassung: | The influence of methyl phenyl ketone and diphenyl ketone on the kinetics of cyclohexanol oxidation initiated by cumyl peroxide at 373 K was studied. The ratio of the chain propagation rate constant involving the 1-hydroxy-1-phenylethylperoxy radical to the equilibrium constant of radical dissociation into methyl phenyl ketone and hydroperoxy radical (
