The role of the Na and of the Ti on the synthesis of ETS-4 molecular sieve

In this paper the synthesis, the crystallisation kinetics and the characterization of Titanium molecular sieve ETS-4 are reported. This ETS-4 material has an open structure, with tetrahedral and octahedral primary building units. The effect of varying of the single reagents amount in the reaction mixture on kinetic parameters, on gel preparation and on properties of the final products is discussed.
