Abstract:
1. A method for preparing a NES-type zeolite, comprising: (a) preparing a reaction mixture comprising (1) at least one active source of an oxide selected from the group consisting of oxides of silicon, germanium, and a mixture thereof; (2) at least one active source of an oxide selected from the group consisting of oxides of aluminum, boron, iron, gallium, and mixtures thereof; (3) at least one active source of an element selected from Groups 1 and 2 of the Periodic Table; (4) hydroxide ions; (5) a structure directing agent selected from the group consisting of 1,4-bis(N,N-dimethylcyclohexylammonium)butane dications and 1,5-bis(N,N-dimethylcyclohexylammonium)pentane dications; and (6) water; and (b) maintaining the reaction mixture under conditions sufficient to form crystals of the NES-type zeolite.
