DIBENZYLPHENOLIC ANTIOXIDANT COMPOUND AND MANUFACTURE

摘要

Phenols having an unsubstituted ortho-or para-position may be benzylated by reaction with a benzyl alcohol in contact with an activated alumina catalyst, especially gamma-alumina, at a temperature sufficient to maintain the reactants in the vapor phase. Particularly disclosed are 2, 6-dibenzyl-4-substituted phenols which are optionally substituted in the 3 and 5 positions. The 2, 6-dibenzyl-4-substituted compounds show good antioxidant activity.
