Title (EN) PROCESS FOR PRODUCING SEC-BUTYLBENZENE
(FR) PROCÉDÉ DE FABRICATION DE SEC-BUTYLBENZÈNE
Abstract: front page image
(EN)A process for producing sec-butylbenzene comprises reacting benzene with at least one linear butene under alkylation conditions and in the presence of a catalyst comprising at least one molecular sieve having an X-ray diffraction pattern including d-spacing maxima at 12.4±0.25, 6.9±0.15, 3.57±0.07 and 3.42±0.07 Angstrom to produce an alkylation product comprising sec- butylbenzene. Prior to the reacting, the catalyst is contacted with water under conditions to improve the sec-butylbenzene selectivity of the catalyst.
(FR)L'invention porte sur un procédé de fabrication de sec-butylbenzène qui comprend la réaction du benzène avec au moins un butène linéaire dans des conditions d'alkylation et en présence d'un catalyseur comprenant au moins un tamis moléculaire ayant un motif de diffraction des rayons X comprenant des maximums d'espacement d à 12,4 ± 0,25, 6,9 ± 0,15, 3,57 ± 0,07 et 3,42 ± 0,07 angström pour donner un produit d'alkylation comprenant du sec-butylbenzène. Avant la réaction, le catalyseur est mis en contact avec de l'eau dans des conditions permettant d'améliorer la sélectivité du catalyseur vis-à-vis de sec.-butylbenzène.
