Use of stabilized pillared interlayered clays as catalyst in alkylation reactions

A method for carrying out a process capable of catalysis by protons using as catalyst a cation-exchangeable solid material characterised in that

• the cation-exchangeable solid material is a stabilised pillared interlayered clay, and
• the process capable of catalysis by protons is a process for the production of an alkyl aromatic compound by reacting an aromatic compound with either an alcohol or an olefin.
