CA 2626527

An all-silica zeolite having the IFR framework topology can be directly synthesized by preparing a reaction mixture comprising (1) an active source of silicon oxide, (2) a structure directing agent comprising a N-benzyl-l,4- diazabicyclo[2.2.2] octane cation, (3) an active source of hydroxide and (4) water and maintaining the reaction mixture under conditions sufficient to form crystals of the zeolite.

L~invention concerne une zéolithe entièrement composée de silice présentant une structure IFR, ladite zéolithe pouvant être directement synthétisée en préparant un mélange réactionnel comprenant (1) une source active d~oxyde de silicium, (2) un agent dirigeant la structure comprenant un cation N-benzyl-1,4-diazabicyclo[2,2,2] octane, (3) une source active d~hydroxyde et (4) de l~eau et en maintenant le mélange réactionnel dans des conditions suffisantes pour former des cristaux de zéolithe.
