Study of alkene epoxidation in the presence of extruded silicalite titanium

Resumo

Main features of liquid-phase epoxidation of propylene, allyl chloride, and allyl alcohol by aqueous solution of hydrogen peroxide in the presence of extruded titanium silicalite in methanol medium have been investigated. The effects of the solvent, the initial ratio of the organic substrate: hydrogen peroxide, and temperature on the yield of main products and by-products were elucidated. Based on the obtained features the conditions for the synthesis of propylene oxide, epichlorohydrin, and glycidol in a laboratory continuous set-up were established.
