ABSTRACT:
A process is disclosed for the alkylation of an aromatic hydrocarbon with an olefin-acting alkylating agent. The aromatic hydrocarbon is commingled with a first portion of said alkylating agent in a first alkylation reaction zone at alkylation reaction conditions in contact with a hydrofluoric acid catalyst. The acid phase of the effluent from the first alkylation reaction zone is separated, and the hydrocarbon phase, comprising alkylate and unreacted aromatic hydrocarbon is commingled with a second portion of said alkylating agent at alkylation reaction conditions in a second alkylation reaction zone in contact with a hydrofluoric acid catalyst separately charged thereto, the hydrofluoric acid catalyst being that separated from the effluent of the first alkylation reaction zone. The acid phase is separated from the effluent from the second alkylation reaction zone and recycled to the first alkylation reaction zone, and the alkylate product is recovered from the hydrocarbon phase.
