Изучали влияние пирокатехина на процесс окисления пропанола-2 кислородом воздуха при радиолизе его 1 М водных растворов. Присутствие в растворе пирокатехина снижало интенсивность окисления и образование ацетона. При совместном присутствии в растворе пирокатехина и ионов железа (ІІ) наблюдали усиление окисления и возрастание выхода ацетона с ростом концентрации ионов Fe+2. Показано, что ионы железа способны подавлять антиоксидантное действие дифенольного антиоксиданта пирокатехина.</p></abstract><trans-abstract xml:lang="en"><p>Antioxidant system of malignant cells interferes with cancer chemotherapy. The influence of pyrocatechol on the oxidation of propanol-2 by atmospheric oxygen during the radiolysis of its 1 M aqueous solutions was studied. Adding 0.01 M pyrocatechol to the solution reduced the intensity of oxidation and the formation of acetone. The yield of acetone increased with the joint presence of pyrocatechol and iron ions in solution. It has been shown that Fe2+ ions can suppress the antioxidant effect of the diphenolic antioxidant pyrocatechol.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>окисление</kwd><kwd>антиоксидантная защита</kwd><kwd>подавление антиоксидации</kwd><kwd>ионы железа</kwd></kwd-group><kwd-group xml:lang="en"><kwd>oxidation</kwd><kwd>antioxidant protection</kwd><kwd>suppression of antioxidation</kwd><kwd>iron ions</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Watson, J.
