Abstract

The vapour-phase alkylation of phenols, to give mainly o-alkylphenols, is effected with alcohols in presence of a rare-earth oxide catalyst. Examples describe the production of o-cresol from phenol and methanol; minor amounts of anisole, o-methylanisole, m- or p-cresols and xylenols are also formed.
