| Outline of Final Research Achievements |
Development of highly-active heterogeneous Ni(II) or Cr(III) catalysts for ethylene oligomerization was investigated in this study. The Ni(II) catalyst was prepared by the intercalation of alfa-diimine ligand into nickel(II) ion-exchanged fluorotetrasilicic mica interlayers. The catalyst showed high activity of ethylene oligomerization, but the products included internal and branched olefins, beside alfa-olefins as target products. The Cr(III) catalyst was also prepared according to the same manner of the Ni(II) catalyst. However, the prepared catalyst did not show any significant activity for ethylene oligomerization. Meanwhile, the catalyst prepared by immobilization of the Cr(III) complex onto an acid-treated montmorillonite showed moderate activity for the reaction. The distorted structure of the complex formed in the mica interlayers changed the properties of the complex, because X-ray diffraction analysis indicated the formation of the Cr(III) complex.
