  • Patent number: 8058494
    Abstract: A process for the production of phenylalkanes comprising at least two catalytic alkylation reactors placed in parallel among which are present in reaction zones that each contain at least one acidic solid catalyst, whereby n is greater than or equal to 2, is described. One of the reactors carries out the alkylation of at least one aromatic compound by at least one olefin that has 9 to 16 atoms. An olefin fraction is introduced at the inlet of each of the reaction zones of the reactor that operates in alkylation mode. While one of the reactors carries out the alkylation, the other reactor carries out the reactivation of each catalyst, partially deactivated, that it contains. The functions of each reactor are switched regularly so as to limit the deactivation of catalysts in each of the reactors. The phenylalkanes that are obtained by the process according to the invention are particularly suitable for the production of detergents.
