Observing the catalytic activity of novel titanosilicates in reactions with hydrogen peroxide
Original language description
Titanium-containing zeolite-based catalysts have been synthesized and investigated as catalysts in methyl (phenyl)sulfide oxidation with hydrogen peroxide. A hierarchical TS-1 was prepared by the secondary templating and a layered TS-1 without and with silica and silica-titania pillars. The study deals with observation of the different catalytic performance with regard to textural properties; presence and volume of mesopores and different diffusion characteristics. All tested catalysts have shown after 240 min almost total conversion of methyl (phenyl)sulfide with different selectivity (substrate/catalyst mass ratio 10). The Ti-pillared TS-1 has shown, during the reaction progress, a decrease in the selectivity to sulfoxide from initial 60% to final 20% of sulfoxide at almost total conversion. The only case when higher selectivity to sulfone was achieved was gradual dosing of hydrogen peroxide.
