| titleOfInvention | Oxygen bridge binuclear allyl silicon bridge amino zirconium catalyst and its preparation method and application |
| abstract | The invention provides an oxygen-bridged allyl-silicon-bridged amino zirconium catalyst, a preparation method and application thereof, and relates to an ethylene polymerization IVB transition metal catalyst, in particular an allylic catalyst with N-C-C-Si-N skeleton Ligand-based zirconium complex catalyst. Its preparation method: under the protection of nitrogen, dehydrogenation of the substituted ketimine with lithium diisopropylamide (LDA), adding equimolar magnesium bromide to obtain magnesium salt, then adding equimolar silane compound A neutral compound is obtained, the allyl silicon bridged lithium amide compound L is prepared through secondary lithiation, and finally reacted with ZrCl 4 and an appropriate amount of oxygen is introduced to obtain the oxygen bridged binuclear allyl silicon bridged zirconium zirconium catalyst C. The preparation method is simple, the materials are simple and easy to obtain, and the price is low; the catalyst shows high catalytic activity when used for ethylene polymerization. |
