A process for the selective alkylation of phenol or its alkyl ethers, in the presence of a particular type of zeolite catalyst, to produce a product rich in 4-alkyl phenyl alkyl ethers (e.g. 4-methylanisole). The zeolite is characterized by a Constraint Index of 1 to 12 and a silica to alumina mole ratio of at least 12, and may optionally contain a minor amount of a difficultly reducible oxide. |
