Activation Procedure titanium silicalite and its use in processes of oxidation with hydrogen peroxide.

It DESCRIBED a process for improving the catalytic role of the titanium silicalite having the formula: XTIO SUB, 2 (1-x) SiO2. In the formula 0.0001 x ranges from 0, 04 CATALYST ACTIVATION (L) in an aqueous medium with hydrogen peroxide PRECURSORS IN THE PRESENCE OF FLUORIDE IONS OR SAMPLES CONTAINING Anionic FLUOR. The activated catalyst (L) is preferably used in oxidation processes with hydrogen peroxide SUBSTRATES ORGANIC AND, IN PARTICULAR, hydroxylation reactions of aromatic compounds ammoximation reactions of carbonyl compounds, epoxidation reactions of olefinic compounds and oxidation reactions of nitrogenous compounds.
