英文摘要: 2,6- Di (tert-butyl) naphthalene (2, 6-DTBN) was prepared over dealuminated HYzeolite (n(Si)/n(Al)=3.8) catalyst. The results showed that the shape-selective effect of the faujasite is obvious, and the thermodynamic balance exists between 2,6-DTBN and 2,7-DTBN. In other words, the two isomers can transform to each other on the acid sites. Naphthalene conversion of up to 98.43% and beta-sclectivity of 100% were obtained on HY zeolite catalyst under the conditions of n(t-BuOH)/n (naph) = 3, WHSV = 2 h(-1) and theta = 120 degreesC with DTBN (2,6-DTBN + 2,7-DTBN) yield of 74.34% and 2,6-DTBN/2,7-DTBN mass ratio of 6.24.
