A process for producing an alkylated aromatic compound from polyalkylated aromatic compound(s) having bi-alkylated aromatic compound(s) and tri- alkylated aromatic compound(s), comprising the step of contacting alkylatable aromatic compound(s) with the polyalkylated aromatic compound(s) at a transalkylation condition in the presence of a transalkylation catalyst. The transalkylation catalyst has high activity sufficient to achieve a ratio of bi- alkylated aromatic compound(s) conversion over tri-alkylated aromatic compound(s) conversion in a range of from about 0.5 to about 2.5.
La présente invention concerne un procédé de production d~un composé aromatique alkylé à partir d~un/de composé(s) aromatique(s) polyalkylé(s) comprenant un/des composé(s) aromatique(s) bi-alkylé(s) et un/des composé(s) aromatique(s) tri-alkylé(s), comprenant l~étape consistant à mettre en contact un/des composé(s) aromatique(s) alkylable(s) avec le(s) composé(s) aromatique(s) polyalkylé(s) dans des conditions de transalkylation et en présence d~un catalyseur de transalkylation. Le catalyseur de transalkylation possède une forte activité, suffisante pour obtenir un rapport entre la conversion du/des composé(s) aromatique(s) bi-alkylé(s) et la conversion du/des composé(s) aromatique(s) tri-alkylé(s) compris entre environ 0,5 et environ 2,5.
