موضوع به انگلیسی:A novel heterogenized Ni/β-diimine/SBA-15 complex applied for catalytic
ethylene oligomerization
بخشی از متن:
Catalytic oligomerization of ethylene performed with the sterically hindered β-diimine ligand 2-(2,6-diisopropylphenyl)-
amine-4-(2,6-diisopropylphenyl)-imine-2-pentene covalently ancored on SBA-15 mesoporous support
employing the alkosilane 3-chloropropyltrimetoxysilane (CPTMS) for the first time. This material was tested as
catalytic precursors for ethylene oligomerization processes and was characterized using various techniques such
as small-angle XRD, elemental analysis, 1H and 29Si NMR, N2 sorption, gas chromatograph and flame atomic
absorption spectroscopy. The heterogenized complex demonstrated an increase in selectivity for the products of
interest (α-C4).
