| titleOfInvention | A kind of mesoporous polyionic liquid catalyst for atmospheric pressure CO2 cycloaddition reaction, preparation method and application |
| abstract | The invention discloses a mesoporous polyionic liquid catalyst for atmospheric pressure CO 2 cycloaddition reaction, a preparation method and application thereof, and relates to the technical field of preparation of heterogeneous catalysts in organic chemical industry. The binuclear ionic liquid polymerized monomer [C 1 DVIM]Br is obtained by solvothermal reaction of N-vinylimidazole and dibromomethane, and an initiator is added to the polyethylene glycol-water solvent system, and the polymerized monomer completes free radical self-polymerization reaction. The invention adopts cheap polyethylene glycol as solvent and a small amount of water as co-solvent, and the mesoporous polyionic liquid prepared by self-polymerization under the action of initiator has typical polycation skeleton, abundant halogen sites and good thermal stability It can be used as a non-metallic heterogeneous catalyst in the CO 2 cycloaddition reaction with epoxy compounds such as styrene oxide as the substrate under normal pressure, and exhibits excellent catalytic activity and good recovery stability. |
