ABSTRACT:
The present invention provides a process for producing an alkyl ether of a phenol from a phenol and an alcohol at a selectivity and a yield higher than in conventional processes, stably over a long period of time. The process is characterized by alkyl-etherifying a phenol with an alcohol in the presence of an oxide catalyst comprising an alkali metal as a constituent element.
