摘要: A process is described for the preparation of zeolitic catalysts in the form of microspheres, comprising zeolite and oligomeric silica, characterized by a high mechanical resistance. The process consists in subjecting to rapid drying the suspension, to which tetra-alkylorthosilicate is optionally added, resulting from the synthesis of zeolite by hydrothermal treatment at autogenous pressure of the reagent mixture containing tetra-alkylammoniumhydroxide as templating agent, and subjecting the product resulting from the drying to calcination.

摘要: A method is described for improving the catalytic performances of titanium silicalite having formula (I) by the activation of the catalyst (I) in an aqueous medium with hydrogen peroxide, in the presence of precursors of fluoride ions or anionic species containing fluorine. The activated catalyst (I) is particularly useful in oxidation processes with hydrogen peroxide of organic substrates and, in particular, in hydroxylation reactions of aromatic compounds, amoximation reactions of carbonyl compounds, epoxidation reactions of olefinic compounds and oxidation reactions of nitrogenated compounds.
