摘　　要：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.The isopropylation of naphthalene with isopropanol over A1MCM-48 mesoporous molecular sieves was studied, A1MCM-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 A1MCM-48 catalysts for naphthalene conversion was enhanced. High naphthalene conversion of 89.5% was achieved over A1MCM-48 with Si/Al=5.3 under the reaction conditions: n(isopropanol)/n(naphthalene) = 2, temperature T = 250 degreesC, time t = 4 h.
