Abstract

A process for the alkylation of aliphatic hydrocarbons with olefins catalyzed by a silica-based material, characterised in that the surface Si--OH groups of said silica are esterified with a fluoroalkylsulphonic acid of formula CF.sub.3 (CF.sub.2).sub.n SO.sub.3 H, where n is a whole number between 0 and 11, said material having a Hammett acidity Ho.ltoreq.-11.4.
