ABSTRACT OF THE DISCLOSURE A crystalline, porous, synthetic material useful as a molecular sieve, as an ion-exchanger or as a catalyst is of zeolitic character. It contains silicon, titanium and aluminum oxides and corresponds, in its calcined and anhydrous state, to the following empirical formula: p HAlO2 . q TiO2 . SiO2. In this formula, p has a value greater than zero and lower than or equal to 0.050, q has a value greater than zero and lower than or equal to 0.025, and the H+ of HAlO2 can be at least partly replaceable or replaced by cations. The process of pre- paration of this material involves the hydrothermal treat- ment of an aluminium derivative, a titanium derivative and a silicon derivative with a nitrogenous organic base.
