Popis

The range of mesoporous materials with different SiO2/Al2O3 ratio, namely aluminosilicates type Siral, silica and MCM-41, were used as supports for immobilization of MTO. The tested support materials and prepared catalytic systems exhibited high surface area, well-defined regular structure and narrow pore size distribution of mesopores and therefore represent excellent catalysts for various reactions. The immobilized MTO on various supports was tested for preparation of 1,2-epoxyindane using two forms of hydrogen peroxide as oxidation agents, namely aqueous solution of hydrogen peroxide and its anhydrous form, urea-hydrogen peroxide (UHP). The catalysts were successfully used for preparation of 1,2-epoxyindane with achieved 100 % selectivities to desired product at high conversions of indene.
