Abstract
Epoxides are one of the important precursors for the formation of organic compounds with oxygen as they undergo ring-opening reactions easily to form bifunctional compounds. Homogeneous catalysts have been used in producing epoxide compounds. However, as these types of catalysts require further separation processes as well as corrosive issues, heterogeneous catalysts have received massive attention. In this study, natural clay from montmorillonite K10 (MMT-K10) was modified via the incorporation of VO(acac)2 at various concentrations. The result of XRD indicated that the crystalline nature of incorporated MMT-K10 was maintained with the 001 basal spacing calculated to be 9.95 Å. The AAS suggested that VO(acac)2 complex has been successfully incorporated onto MMT-K10 with the increasing amount of vanadium element as the concentration of vanadium complex solution increased. The catalytic activity of the vanadium complex supported on MMT-K10 showed that 20% of cyclohexene was converted with 70% selectivity to cyclohexene oxide using tert-butyl hydroperoxide (TBHP) as the oxidant.
