Abstract
Processes for alkylating benzene are provided. In embodiments, the process comprises combining benzene, an olefin, and a catalyst composition under conditions to react benzene with the olefin to produce an alkylbenzene, the catalyst composition comprising components selected from the group consisting of an ionic liquid, an acid, and an aromatic; an acid, a base capable of forming an ionic liquid with the acid, and an aromatic; an ionic liquid and an acid; and an acid and a base capable of forming an ionic liquid with the acid. The ionic liquid does not comprise a metal halide and the catalyst composition is free of a metal halide and the aromatic, if present in the catalyst composition, is not the benzene being alkylated.
