ABSTRACT:
An aluminosilicate gel containing a structuring agent ST and having a composition appropriate for crystallizing as a zeolite of the faujasite structural family is prepared, and then subjected to a crystallization to form a zeolite precursor consisting of the said zeolite containing the structuring agent ST in its cavities and channels, and zeolite is produced by calcination of the said precursor. The structuring agent ST consists of at least one compound chosen from the polyoxaalkylamines and/or polyoxaarylamines of general formula:
