Abstract

Catalytic performances of USY, MOR, and BEA zeolites were compared for the isopropylation of naphthalene by isopropyl alcohol in a high-pressure, fixed-bed reactor. The USY catalyst showed a high conversion of 86% and good stability but a low 2, 6-/2, 7- DIPN shape selectivity ratio of 0.94. In contrast, over the MOR catalyst, 2, 6-DIPN was selectively synthesized with a high 2, 6-/2, 7-DIPN ratio of 1.75, but low naphthalene ...
