A process for preparation of a MEL-structural-type zeolite that comprises at least the following stages: in which n represents the methylene group number (CH) and is equal to 6 or 7, and R1 and R2 represent alkyl groups that have 2 to 7 carbon atoms,

Process for preparation of a MEL-structural-type zeolite

The invention concerns a crystalline solid designated IZM-1, which has the X ray diffraction diagram given below. Said solid has a chemical composition, expressed as the anhydrous base in terms of moles of oxides by the formula XO: aYO; bMO where X represents at least one tetravalent element, Y represents at least one trivalent element and M is an alkali metal and/or an alkaline-earth metal with valency n, a and b respectively representing the number of moles of YOand MO; a is in the range 0 to 0.02 and b is in the range 0 to 1.

IZM-1 crystalline solid and a process for its preparation

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.
