Abstract
Process for the synthesis of alkylated aromatic hydrocarbons containing a saturated alkyl chain comprising at least four carbon atoms, according to which an aromatic hydrocarbon substituted by a saturated short-chain alkyl group comprising one to three carbon atoms is reacted with an olefin in the presence of a catalyst which comprises at least one alkali metal or one alkali metal hydride impregnated on an alumina support and the catalyst is prepared in the reaction medium in the presence of the aromatic hydrocarbon containing a short alkyl chain by mixing anhydrous alumina with the alkali metal hydride or with the alkali metal, the ratio by weight of the alkali metal or of the alkali metal hydride to the alumina support being between 0.6 and 1.8. Use of the process for the synthesis of tert-amylbenzene by alkylation of cumene with ethylene.
