Study and Immobilization of ephedrine onto the nanopores of mesoporous material SBA- 16 and complexation with molybdenum for preparation of heterogeneous catalyst for epoxidation of olefins

New heterogeneous molybdenum catalystwas prepared through covalent attachment of ephedrineligand on the surface of mesoporous SBA-16 viachloropropyl spacer and subsequent complexation withMoO2(acac)2. The prepared nanocatalyst wascharacterized with Fourier transform infraredspectroscopy, X-ray diffraction, transmission electronmicroscopy and atomic adsorption spectroscopy.Catalytic epoxidation of cyclooctene and cyclohexene byprepared nanocatalyst using cumene hydroperoxide asoxidant was achieved with high selectivities.
