Abstract

PURPOSE: To carry out the orthoalkylation of a phenolic compound, selectively, by using a highly active and long-life catalyst containing chromium oxide modified with at least one kind of compounds of alkali metals or alkaline-earth metals.
CONSTITUTION: A phenolic compound having at least one H at the ortho position and an alcohol are subjected to the vapor-phase catalytic reaction at 260W520°C, using a catalyst containing chromiun oxide which is obtained by modifying (A) a catalyst containing chromium oxide alone or containing chromium oxide as the main and besides at least one kind of metal oxides of tin, iron, manganese, etc. or/and sulfate group, etc., with (B) at least one kind of compounds of alkali metals or alkaline-earth metals, by kneading, dipping, etc., whereby the phenolic compounds is selectively orthoalkylated to give the alkylphenol.
USE: Raw materials for polyphenylene oxide, etc.
