Abstract
The invention relates to a process for preparation of a zeolite that is selected from among the ZBM-30, ZSM-48, EU-2 and EU-11 zeolites, comprising the mixing in an aqueous medium of at least one source of at least one element X (Si and/or Ge) and at least one nitrogen-containing organic compound Q. Said nitrogen-containing organic compound Q is selected from among the compounds comprising at least one ether group and two terminal ammonium groups and their precursors.
Claims18
