Abstract: | The effects of some aminophenol derivatives, diphenylamine, and ionol on the formation of ethanol and hexane radiolysis products in aerated and deaerated solutions were studied. The results allowed conclusions to be made about the effect of the structure of test compounds on their reactivity to oxygen- and carbon-centered radicals. It was found that 4,6-di-tert-butyl-2-(N-acetylamino)phenol, 4,6-di-tert-butyl-2-(N-benzoylamino)phenol, 2-hydroxydiphenylamine, and 4-hydroxydiphenylamine were highly competitive with commercial antioxidants in the efficiency of inhibition of radiation-induced processes of hexane oxidation. N-(2-Hydroxy-3,5-di-tert-butylphenyl)aniline, 4,6-di-tert-butyl-2-cyclohexylaminophenol, 2-hydroxydiphenylamine, 4-hydroxydiphenylamine, and N-phenyl-1,4-benzoquinonemonoimine were superior to ionol and diphenylamine in the inhibition of reactions of alkyl and -hydroxyalkyl radicals. |
