| titleOfInvention | Preparation method of aliphatic cyclic polycarbonate |
| abstract | The invention discloses a preparation method of cyclic carbonate, which adopts alkene, aldehyde and carbon dioxide to convert into more valuable cyclic carbonate chemicals, wherein the carbon dioxide is in a supercritical state and is used as a reactant and a solvent, and the method also adopts a novel composite heterogeneous nano catalyst material for simultaneously activating the carbon dioxide and the alkene and is used for jointly activating the carbon dioxide and the alkene to realize the purpose of preparing the cyclic carbonate by high-yield conversion under mild conditions. The method has the advantages of cheap and easily-obtained raw materials, non-corrosive catalyst, simple operation of the technological process without other reaction steps, high efficiency, simplicity, practicability, economy and no pollution, and is favorable for large-scale industrial production of the cyclic carbonate. |
