Alkylation of aromatics using a fluorided silica-alumina catalyst

U.S. Patent Number: 5344997

Abstract: A fluorided silica-alumina catalyst, particularly one with a silica:alumina ratio in the range of 1:1-9:1 containing from 1 to 6 weight percent fluoride, is particularly effective in the liquid phase alkylation of benzene by linear olefins to produce linear alkyl benzenes at temperatures no greater than 140.degree. C. These catalysts also are effective in the liquid phase alkylation of alkylatable aromatics generally with a variety of alkylating agents, including olefins, alcohols, and alkyl halides.
