1. A process for alkylating benzene, the process comprising 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
(a) an ionic liquid, an acid, and an aromatic; and
(b) an acid, a base capable of forming an ionic liquid with the acid, and an aromatic;
wherein the ionic liquid does not comprise a metal halide and the catalyst composition is free of a metal halide and the aromatic is not the benzene being alkylated.
