【Abstract】 HY, Hβ and HM zeolites were synthesized and characterized by XRD, NH 3-TPD and Py-IR. Selectively catalytic alkylation of naphthalene with n-hexanol to hexyl-naphthalene over the zeolites has been examined. The experimental results show that HY zeolite can be used as a catalyst for the title reaction and shows a higher naphthalene conversion. Higher reaction temperature and longer reaction time are beneficial for the production of β-hexyl-naphthalene over HY zeolite.更多还原
