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.
Claims11
A process of alkylating an alkylatable aromatic compound with an alkylating agent comprising reading in the liquid phase the alkylatable aromatic compound with the alkylating agent under alkylating conditions in the presence of an alkylation catalyst comprising a fluorided silica-alumina containing from about 1 to about 6 weight percent fluorine.
