Abstract
Process for the synthesis of faujasite, having a Si/Al ratio greater than 1 and which can exceed 3, in the presence of a structuring agent consisting of at least one carbonaceous macrocycle having 10 to 24 atoms per ring and containing heteroatoms chosen from oxygen, nitrogen, sulphur or silicon, the macrocycle being introduced into the reaction medium in the form of a crude synthetic sodium complex.
