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.

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.

Abstract: Provided herein are compositions and methods for degrading polymer systems. These compositions and methods can be used to effectively degrade a range of polymers commonly used in oil and gas operations, including polymers with carbon-carbon backbones such as polyacrylamides. Further, these compositions and methods can simultaneously degrade other organic molecules and pollutants associated with oil and gas operations. The compositions and methods described herein employ reactants that are more environmentally-friendly than conventional methods and components used in, for example, polymer breaking processes.
