Abstract
Alumina or zirconia pillared fluorotetrasilicic mica and montmorillonite were used as catalysts for the alkylation of naphthalene with t-butyl alcohol, and their catalytic activity and selectivity for the formation of 2, 6-di-t-butylnaphthalene were studied. In comparison with silica-alumina and HY zeolite, the pillared clays gave high yield of di-t-butylnaphthalenes. Selectivity for the formation of 2, 6-di-t-butylnaphthalene is correlated well with selectivity for adsorption of 2, 6-di-t-butylnaphthalene, indicating that selective formation of 2, 6-isomer may be attributed to molecular sieving effect of pillared clays.
