Abstract : A connection was established between the radical interaction of two inhibitors, an aromatic amine (N-phenyl-beta-methylamine) and substituted phenols, and the structure of the phenols. This phenomenon is observed for o,o'-substituted alkylphenols and it is not observed for o,o'-nonsubstituted and o-substituted alkylphenols. The rate of amine reduction by phenol is determined by the activity of the formed phenoxyl radical. The rate constants of the interaction of substituted phenols with RO2 radicals in the oxidation of ethylbenzene were measured. They established a connection between the effectiveness of the phenols and their structure. The activation energy of the reaction of 2, 4, 6-tri-tert-butylphenol with peroxide radicals was determined to be 3.4 kcal/mole.
