Abstract:
A process for producing arylalkanes, the process comprising contacting an olefin feed comprising monoolefin molecules having from about 8 to about 28 carbon atoms and having 3 or 4 primary carbon atoms with no guaternary carbon atoms with an aryl compound at alkylation conditions in the presence of a zeolite having an NES zeolite structure type, wherein the arylalkanes comprise molecules comprising one aliphatic alkyl portion and one aryl portion; the aliphatic alkyl portion has from about 8 to about 28 carbon atoms, has 2, 3, or 4 primary carbon atoms, and has no quaternary carbon atoms except for any quaternary carbon atom bonded by a carbon-carbon bond with a carbon atom of the aryl portion; and the process has a selectivity to 2-phenyl-alkanes of from 40 to 100 and a selectivity to internal quaternary phenyl-alkanes of less than 10.
