Abstract
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.
