A manganese(II)-Schiff base complex has been heterogenized by its intercalation into clay minerals. The incorporation of the homogeneous manganese(II) complexes in the interlayer space of aluminosilicate mineral is accomplished by a cation exchange process. The obtained clay-manganese(II) composite has been studied by chemical analysis, X-ray diffraction and FT-IR spectroscopy. The new catalytic material has been evaluated as oxidation catalyst. Our results showed that this composite exhibits significant catalytic activities for alkene epoxidation using hydrogen peroxide as oxidant. (C) 2002 Elsevier Science B.V. All rights reserved.
