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-1,4-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.
