Abstract
Processes for acylating an aromatic compound are provided. In embodiments, such a process comprises combining an aromatic compound, an acylating agent, and a catalyst composition under conditions to induce acylation of the aromatic compound with the acylating agent, the catalyst composition comprising components selected from the group consisting of a sulfonic acid of formula R—SO3H, wherein R is a linear alkyl group substituted with one or more halogen atoms; an ionic liquid and an acid; an acid and a base capable of forming an ionic liquid with the acid; an ionic liquid, an acid, and an aromatic; and an acid, a base capable of forming an ionic liquid with the acid, and an aromatic. 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 aromatic compound being acylated.
