Abstract: The isopropylation of naphthalene with isopropanol over AlMCM48 mesoporous molecular sieves was studied. AlMCM48 showed high activity and shape selectivity to the isopropylation of naphthalene. Grafting aluminum on MCM48 improved its acidity. It was found that with the increasing of Al content, the performance of AlMCM48 catalysts for naphthalene conversion was enhanced. High naphthalene conversion of 89.5 % was achieved over AlMCM48 with Si/Al=5.3 under the reaction conditions:n(isopropanol) /n(naphthalene)=2, temperature T=250 ℃, time t=4 h.

Key words: MCM-48, Naphthalene, Isopropylation
