Abstract
Abstract Liquid phase alkylation of naphthalene with tert-butyl alcohol over HY zeolites modified with acid and alkali had been studied. A highest naphthalene conversion of more than 90 mol% was achieved over HY zeolites modified with hydrochloric acid (HY-H). 2,6-di-tert-butylnaphthalene(DTBN) was synthesized selectively over HY zeolites modified with oxalic acid (OY) and with stepwise acid and alkali (OSY-BS-H), with 2,6-/2,7-DTBN ratios of 5.93 and 6.11, respectively. Correlations between 2,6-selectivity and zeolite structures, catalysts acidity, products properties were obtained.
