ABSTRACT:
A process for the alkylation of aromatic compounds employing silicalite of extremely low sodium content. A feedstock containing an aromatic substrate such as benzene is supplied along with an alkylating agent such as ethylene to a reaction zone containing a silicalite alkylation catalyst having a sodium content of less than 100 ppm Na.sub.2 O. Steam may be cofed to the reaction zone in an amount of at least 1 wt. % based upon the aromatic substrate. The low sodium silicalite has a substantially better aging quality in the alkylation process than does silicalite which normally has a higher sodium content.
