Abstract
A method of alkylating aliphatic or aromatic hydrocarbons with olefins using solid hydrogen fluoride-equivalent catalysts is described. Preferred catalysts comprise solid polymeric onium polyhydrogen fluoride complexes.
Claims21
A method of alkylating an aliphatic or aromatic hydrocarbon with an olefin, which comprises contacting the aliphatic or aromatic hydrocarbon with the olefin in the presence of a solid polymeric onium polyhydrogen fluoride complex under conditions sufficient for the alkylation of the aliphatic or aromatic hydrocarbon.
A process for forming a solid polymeric onium polyhydrogen fluoride complex, which comprises contacting a homopolymer or copolymer including, in at least one repeat unit, a nitrogen, phosphorus, or sulfur atom, capable of forming an onium fluoride moiety upon reaction or complexation with a source of hydrogen fluoride under conditions sufficient to form the solid polymeric onium polyhydrogen fluoride complex.
A process for removing hydrogen fluoride from an alkylation product, which comprises contacting the alkylation product with a homopolymer or copolymer including, in at least one repeat unit, a nitrogen, phosphorus, or sulfur atom, capable of forming an onium fluoride moiety upon reaction or complexation with a source of hydrogen fluoride, under conditions sufficient for the homopolymer or copolymer to complex hydrogen fluoride.
