Abstract
A fluorided silca-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 to produce linear alkyl benzenes at temperatures no greater than 140.degree. C. Conversions in excess of 98% with selectivity exceeding 85% and linearity exceeding 90% may be achieved readily.
