| titleOfInvention | Preparation method and application of metal-free catalyst |
| abstract | The invention discloses a preparation method of a metal-free catalyst, which takes dicarboxylic acid derivatives and triazine nitrogen heterocyclic organic matters as raw materials, and the catalyst is prepared by reacting for 48-72 hours at 65-150 ℃ in the presence of a solvent, cooling to room temperature after the reaction is finished, filtering, washing the reaction product with the solvent, and drying; the metal-free catalyst can react CO without a cocatalyst and a solvent 2 The catalyst and epoxide are converted into cyclic carbonate, and the cyclic carbonate has the advantages of obvious catalytic effect, high selectivity, mild reaction condition and repeated recycling. |
