ABSTRACT:
A method of alkylating phenols which comprises reacting phenols having a hydrogen atom in at least one of the ortho-positions with regard to the hydroxyl group with an alcohol in a gaseous phase under heat in the presence of a catalyst comprising iron oxide, silica, chromium oxide, germanium oxide and an alkali metal compound. The catalyst exhibits a long catalytic activity duration and decreases frequency of regeneration and replacement of catalysts.
