Abstract
1. The influence of methyl, ethyl, and tert-butyl alcohols on the effectiveness of the action of inhibitors (phenol derivatives) in the oxidation of methyl ethyl ketone was investigated. 2. When methyl ethyl ketone is diluted by alcohols, the effective rate constant of the interaction of peroxide radicals of methyl ethyl ketone with the inhibitor drops. 3. The decrease in the effectiveness of inhibitors in alcohol solutions of methyl ethyl ketone is associated with the ability of alcohols to form a hydrogen bond with inhibitor molecules and with peroxide radicals of methyl ethyl ketone. 4. For solutions of methyl ethyl ketone in tert-butyl alcohol, values of the rate constants of the elementary steps of the reactions of RO2. with inhibitors and the equilibrium constants of the formation of hydrogen bonds between the alcohol and inhibitor molecules were obtained. The results were compared with the data obtained in the oxidation of methyl ethyl ketone in aqueous solutions.
