CATALYTIC STEAM DEALKYLATION OF ALKYL PHENOLS

摘要

This invention provides a method for the selective dealkylation of alkylated phenols, which method comprises reacting a feed solution comprising a mixture of alkylated phenols with steam in the presence of a catalyst comprising a hydrous carrier, at least one catalyst deactivation suppressor and at least one promoter. A salt of an alkali metal may be added to the feed to enhance the selectivity. for phenol in the product.
