ABSTRACT:
Aromatic hydrocarbons are selectively alkylated using an alkylating mixture containing both ethylene and propylene. By employing a zeolite ZSM-12 based alkylation catalyst, essentially only the propylene from the olefin-containing alkylation mixture will react with the aromatic hydrocarbon to thereby form both an alkylaromatic product enriched in propylated alkylaromatic and a propylene-free residual olefin-containing mixture enriched in the unreacted ethylene.
