Chukicheva (2) Abstract: The stoichiometric factors of inhibition and the rate constants (k .sub.7) were measured for the reaction of isobornylphenols with peroxy radicals of ethylbenzene. The values of k .sub.7 of the compounds under study increase with an increase in the amount of alkyl substituents and OH groups on the aromatic ring. The introduction of the oxygen atom between the o-isobornyl substituent and the aromatic ring decreases k .sub.7 by a factor of 6.5. The inhibiting action of binary mixtures of sterically hindered phenols with 2-isobornyl-4-methylphenol and 2,6-diisobornyl-4-methylphenol in the initiated oxidation of ethylbenzene is close to additive.
