| titleOfInvention | Octanuclear N-alkoxy-β-ketimine magnesium complex and its preparation method and application |
| abstract | The invention belongs to the field of complex preparation and application, and discloses an octanuclear N-alkoxy-β-ketimine magnesium complex and a preparation method and application thereof. In an argon atmosphere, Mg(n-Bu) 2 was added dropwise to the β-ketimine ligand solution in the temperature range of 0°C-25°C, and reacted in the temperature range of 0°C-55°C for 3 h to obtain octanuclear N-alkoxy-β-ketimine magnesium complex. The application of the octanuclear N-alkoxy-β-ketimine magnesium complex prepared by the method includes the application in catalyzing the ring-opening polymerization of lactide. Under solution and bulk conditions, polylactide can be prepared by catalyzing the polymerization of lactide without the participation of a co-catalyst. The catalyst has the advantages of simple preparation method, novel structure and high catalytic activity. The polymer obtained by the reaction has a narrow molecular weight distribution and a controllable molecular weight. |
