<p>This invention is a process for the monoalkylation or dialkylation of aromatic (preferably biphenyl compounds) to produce alkylated aromatics (particularly dialkylated biphenyl compounds), using specific catalysts (preferably dealuminated mordenite) having an Si/Al ratio between 5 and 100 and having 27Al-MAS-NMR ratio less than about 5.</p> |
