Popis: Initiated oxidation of cumene with oxygen in the presence of various phenol antioxidants and a supramolecular system containing the oxygen radical anion of was studied. It is shown that superoxide anion and ionol, hydroquinone, and ethyl gallate are the antagonists in the process of inhibition of the radical chain oxidation. Simultaneous introduction of the ascorbic acid and the radical anion of oxygen caused the synergistic effect.
