Title
(EN) PROCESS FOR THE SYNTHESIS OF AROMATIC ALKYLATED HYDROCARBONS
(FR) PROCEDE POUR LA SYNTHESE D'HYDROCARBURES AROMATIQUES ALKYLES
Abstract
(EN)
Process for the synthesis of aromatic alkylated hydrocarbons with a saturated alkyl chain including at least four carbon atoms, according to which an aromatic hydrocarbon, replaced by an alkyl group with a short saturated chain comprising one to three carbon atoms, is made to react with an olefin in the presence of a catalyst made up of at least one alkaline metal or a alkaline metal hydride impregnated on an alumina support. The process is characterised by the fact that the catalyst is prepared in the reaction medium in the presence of the aromatic hydrocarbon with a short alkyl chain by mixing anhydrous alumina with the alkaline metal hydride or with the alkaline metal, and then the olefin is introduced in order to start the reaction.

Procédé de synthèse d'hydrocarbures aromatiques alkylés à chaîne alkyle saturée comprenant au moins quatre atomes de carbone selon lequel on fait réagir un hydrocarbure aromatique substitué par un groupement alkyle à chaîne courte saturée comportant de un à trois atomes de carbone avec une oléfine en présence d'un catalyseur constitué d'au moins un métal alcalin ou un hydrure de métal alcalin imprégné sur un support d'alumine caractérisé en ce que l'on prépare le catalyseur dans le milieu réactionnel en présence de l'hydrocarbure aromatique à courte chaîne alkyle par mélange de l'alumine anhydre avec l'hydrure de métal alcalin ou avec le métal alcalin, puis on introduit l'oléfine pour démarrer la réaction.
