Abstract: H-type zeolites(HY, Hβ, and HM) were synthesized and characterized by XRD, NH3-TPD, and Py-IR.Selectively catalytic alkylation of naphthalene with n-hexanol to hexyl-naphthalene over the zeolites was carried out.The experimental results show that the catalytic activities of the zeolites are mainly determined by their acid properties and pore structures.The larger the pore diameter is, the higher the catalytic activity is.NH3-TPD profiles show that Hβand HM have lower acid strengths than HY.HY has both the highest activity and highest selectivity for the hexylnaphthalene.Higher reaction temperatures and longer reaction time are beneficial to the production of β-hexyl-naphthalene over the HY zeolite.

Key words: H-type zeolites, Naphthalene, n-Hexanol, Hexylnaphthalene, Alkylation
