2,6-Bis(3,5-di-tert-butyl-4-hydroxybenzyl)cycloalkanone: Synthesis and prospects for use as stabilizer for ethylene-propylene rubber

A phenolic antioxidant was synthesized by the reaction of N,N -dimethyl(3,5-di- tert -butyl-4-hydroxybenzyl) amine with cyclohexanone. The infl uence of temperature, reactant ratio, pressure, and time on the yield of the product, 2,6-bis(3,5-di- tert -butyl-4-hydroxybenzyl)cyclohexanone, was examine...

Summary:A phenolic antioxidant was synthesized by the reaction of N,N -dimethyl(3,5-di- tert -butyl-4-hydroxybenzyl) amine with cyclohexanone. The infl uence of temperature, reactant ratio, pressure, and time on the yield of the product, 2,6-bis(3,5-di- tert -butyl-4-hydroxybenzyl)cyclohexanone, was examined. The antioxidant obtained, taken both separately and in synergistic mixtures with alkylphenol and phosphites, showed high performance in inhibition of the thermal aging of ethylene-propylene rubber.
