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

摘要

The present invention relates to a method of using hydrogen peroxide as a catalyst 1 in an aqueous medium, by activating in the presence of an anionic species containing precursor or fluoride of the fluoride ion, to improve the catalytic performance of titanium silicalite of formula will be. ; 1 is an active catalyst for oxidation of organic substances with hydrogen peroxide, in particular, it is especially useful for the oxidation reaction of the epoxidation reaction and a nitrification reaction of the compounds of the hydroxy aromatic compound, an olefin compound.
