Abstract
A process for synthesising a zeolite with structure type EUO comprising at least one element X selected from silicon and germanium and at least one element T selected from aluminum, iron, gallium, boron, titanium, vanadium, zirconium, molybdenum, arsenic, antimony, chromium and manganese, comprises reacting an aqueous mixture comprising at least one source of at least one element X, at least one source of at least one element T, and at least one precursor of an organic compound comprising at least one alkylated polymethylene &agr;-&ohgr; diammonium derivative, wherein at least one precursor is selected from monoamines. The zeolite obtained is used as a catalyst in a process for converting hydrocarbon-containing feeds, as an adsorbent to control pollution and as a molecular sieve for separation, and particularly for isomerising aromatic compounds containing 8 carbon atoms.
