PROCEDE DE PRODUCTION DE PHENYLALCANES UTILISANT UNE COMBINAISON DE DEUX CATALYSEURS

摘要

The invention concerns a method for producing phenylalkanes by alkylation of at least an aromatic compound using at least a linear olefin having 9 to 16 carbon atoms per molecule. The alkylation reaction is carried out in the presence of at least two different catalysts used in at least two separate reaction zones. The selectivity in monoalkylated products of the first catalyst contained in the first reaction zone is lower than that of the catalyst contained in the second reaction zone, located downstream of the first in the direction of flow of the fluids.
