Pyrocatechol and Its Derivatives as Antioxidants and Prooxidants

摘要

The effect of pyrocatechol and its derivatives (4,5-dichloro- and 4,5-dibromo pyrocatechols, veratrol, 4,5-dichloro- and 4,5-dibromoveratrol) on the free-radical oxidation of propan-2-ol in aqueous solutions, initiated by γ-radiation. Pyrocatechol and dihalocatechols exhibit antioxidant properties, whereas dihalo-veratrols exhibit prooxidant properties. Dibromoveratrol showed more expressed prooxidant properties.
