Abstract:
Transalkylation of 2,6-di-tert-butyl-4-R-phenols over solid heteropoly acids (H3PW12O40, H4SiW12O40, H3PW12O40/SiO2, H4SiW12O40/SiO2) in the presence of toluene or o-xylene as acceptors of a tert-butyl group at 100–140 °C produces 4-R-phenols with 92–98% yield (R = H, alkyl, aryl, etc.). HPAs are effective catalysts for the transalkylation of p-cresol and 2, 6-ditert-butyl-4-methylphenol.
