Abstract
The invention concerns a process for preparing a copper-comprising microporous aluminosilicate material with AFX structure, comprising at least the steps of mixing, in an aqueous medium, at least one aluminum source, at least one silicon source, at least one copper source, a TETA or TEPA organic complexing agent and a DABCO-C4 structuring agent, in order to obtain a gel, and hydrothermal treatment of said gel with stirring in order to obtain crystallization of said copper-comprising microporous aluminosilicate material with AFX structure.
