Synthesis of phenolic antioxidants with isobornyl and tert-butyl fragments
摘要:
Hybrid antioxidants, phenols with a terpene and tert-butyl substituents, were synthesized by the alkylation of 2-tert-butyl-4-methylphenol with camphene and 2-isobornylphenol with tert-butyl chloride in the presence of acidic heterogeneous catalysts, montmorillonite KSF and FIBAN K-1. Antioxidant activity of the synthesized terpenophenols was evaluated using spectrophotometry.
