Abstract

A process for alkylating aromatic hydrocarbons with C.sub.2 to C.sub.4 olefins and for transalkylating alkyl or poly-alkylaromatic compounds with an aromatic hydrocarbon. A major portion of the aromatic hydrocarbon is recycled to the alkylation zone while the remainder thereof and poly-alkylaromatic hydrocarbons are subjected to transalkylation in a separate transalkylation zone. Mono-alkylaromatics produced in the alkylation zone are separated from the other reaction products prior to transalkylation.
