Popis:	Initiated oxidation of cumene by oxygen in the presence of ascorbic acid was studied. ORGANIC SYNTHESIS AND INDUSTRIAL ORGANIC CHEMISTRY ISSN 1070-4272, Russian Journal of Applied Chemistry, 2011, Vol. 84, No. 3, pp. 427–430. © Pleiades Publishing, Ltd., 2011.

It has been shown previously that ascorbic acid exhibits antioxidant properties in both aqueous and organic phases and, irrespective of the nature of a solvent, the duration of action of vitamin C is determined by its concentration in the system [1, 2]. The concentration range of ascorbic acid in the reaction mixture has been determined, at which its efficiency as an inhibitor of the radical-chain oxidation in the organic medium is the highest. In this study, we continued analysis of the effect of vitamin C at its increased concentrations on the radical-chain oxidation process.
