Abstract:
Ortho-alkylated phenols are prepared by reacting phenol unsubstituted in at least one ortho position with an alcohol in the presence of an ortho-alkylation catalyst consisting of magnesium carbonate, magnesium hydroxide or a mixture of both. The catalyst is used in the absence of a promoter compound and with or without polymeric binder.
