Abstract:
A process for producing at least one compound selected from 2-, 3-, 4-, 5- and 6-phenylalkanes by alkylating benzene in an alkylation zone using at least one olefin containing at least 9 carbon atoms per molecule, in the presence of a solid zeolitic catalyst, characterized in that the catalyst comprises a matrix and a zeolite with structure type EUO having a crystal size less than 0.2 micrometers, said zeolite comprising silicon and at least one element T selected from the group consisting of aluminum, iron, gallium and boron, with an oversall Si/T atomic ratio of more than 5; and characterized in that said alkylation is carried out at a pressure in the range 0.1 to 10 MPa, a temperature in the range of 30Â° C. to 400Â° C., with an hourly space velocity of 0.50 to 200 hâˆ’1, and a benzene/olefin(s) mole ratio in the range of 1:1 to 50:1.
