Abstract
A method of making benzylated phenols comprises contacting a phenol and a benzyl alcohol with a basic metal oxide catalyst at a temperature sufficient to maintain each of the phenol and the benzyl alcohol in a vapor phase. The phenol has at least one hydrogen ortho to its phenolic hydroxyl group.
