The present invention relates to an alkylation process in which, on the one hand, benzene is treated and on the other hand a feedstock comprising at least one compound chosen from the group formed by olefins containing from 2 to 3 carbon atoms per molecule. and alcohols containing from 2 to 3 carbon atoms per molecule, in the presence of an alkylation catalyst comprising a zeolite of structure type EUO, comprising silicon and at least one element T selected from the group formed by aluminum, iron, gallium and boron, (preferably aluminum and boron), with an overall Si / T atomic ratio greater than 5 and with a sodium content of less than 300 ppm. The process comprises recycling the polyalkylated products to the alkylation zone. The process makes it possible to synthesize cumene and ethylbenzene. |
