Abstract
This invention relates to a process for synthesis of an EUO-structural-type zeolite that comprises at least one element X that is selected from among silicon and germanium and at least one element T that is selected from among aluminum, iron, gallium, boron, titanium, vanadium, zirconium, molybdenum, arsenic, antimony, chromium and manganese, whereby said process is carried out in the presence of an organic structuring agent that is derived from dibenzyldimethylammonium (DBDMA) or its precursors and in the presence of nuclei of at least one zeolitic material of the same structure as the zeolite that is to be synthesized. The zeolite that is thus obtained has an X/T ratio of between 5 and 50. It is used in particular as a catalyst, for example in a process for isomerization of aromatic compounds with 8 carbon atoms per molecule.
