The combined addition of two phenols, one of which is sterically hindered, for example, 2,6-bis(l,l-dimethylethyl)phenol, and another is sterically nonhindered also leads to a synergistic effect [35-38]. As found by Mahoney [35], 2,4,6-tris(l,l-dimethylethyl)phenol with a concentration of 10 4 L mol 1 does not virtually inhibit the initiated oxidation of 9,10-dihydroan-thracene (333 K), but /)-methoxyphenol, taken in the same concentration, does inhibit oxidation. The induction period doubles if two phenols are added together in equal concentrations, which indicates that both phenols are involved in chain termination. The mechanism of synergistic action can be explained by the following kinetic scheme [35] ...
