The present invention is directed to a process for preparing NES-type
zeolites using novel nitrogen-based structure directing agents. The
structure directing agents used in preparing NES-type zeolites selected
from the group consisting of 1,4-bis(N,N-dimethylcyclohexylammonium)
butane dications and 1,5-bis(N,N-dimethylcyclohexylammonium) pentane
dications.
