摘要：
Activity and selectivity of niobium-containing mesoporous molecular sieves have been tested in liquid phase oxidation of cyclohexene. On the basis of this investigation the new efficient NbSBA- 15 catalyst prepared from niobium chloride via conventional synthesis, has been selected. Moreover, other NbSBA-15 show high activity in this reaction (the yield of epoxide is higher than 40%). It has been shown that all NbSBA-15 catalysts are efficient in the reaction of cyclohexene oxidation and their activity can be explained with difference in pore diameters.
