Abstract
A catalytic process for the selective alkylation of mono- and polycyclic aromatic hydrocarbons is described. The aromatic hydrocarbon is reacted with an alkylating agent in the presence of an acid form of a dealuminated small pore mordenite catalyst having an atomic ratio Si/Al of at least 10:1 to thereby yield the desired alkyl substituted derivative with improved selectivity and improved yield.
