Abstract

The effects of flavonols and structurally related model compounds on the formation of the final radiolysis products of ethanol and aqueous ethylene glycol and 2-methoxyethanol solutions were studied. It was found that the test compounds actively interact with the α-hydroxyl-containing radicals of parent substances by several mechanisms to change the direction of radiolytic processes. The applicability of flavonols to the inhibition of radiation-induced free-radical fragmentation of organic compounds was demonstrated for the first time. Mechanisms were proposed to explain the observed effects.
