Abstract

The rate constants of the interaction of peroxide radicals with five inhibitors of the class of phenols were measured in the oxidation of cyclohexane in solutions of acetic acid, ethyl acetate, and para-dichloro-benzene.Acetic acid and para-dichlorobenzene have an influence only on account of a change in the strength of the electrostatic interaction between the solvent and the reacting particles.In the case of oxidation in solutions of ethyl acetate, in addition to electrostatic interaction with the medium, specific solvation by the solvent is observed on account of the formation of hydrogen bonds between phenols and ethyl acetate.The equilibrium constants of the formation of hydrogen bonds with ethyl acetate were determined for all the investigated inhibitors.
