ABSTRACT:
This invention is for a shaped, alkylation catalyst comprising magnesium oxide bonded with an inert, organic polymeric binder and to the use of the catalyst in a process for the ortho-alkylation of phenols. The process comprises the vapor phase reaction of a non-ortho-substituted phenol with an alcohol in the presence of the catalyst. The catalyst of the invention is an improvement over prior art catalysts used for ortho-alkylation of phenols as it substantially reduces the induction period for maximum reaction selectivity, eliminates loss of catalyst arising with use of powders and substantially extends catalyst life.
