| titleOfInvention | Method for preparing alkylene carbonate from epoxyalkane and carbon dioxide |
| abstract | The present disclosure relates to a method for preparing alkylene carbonate from alkylene oxide and carbon dioxide. The method comprises: contacting a raw material comprising alkylene oxide and carbon dioxide with a catalyst to produce alkylene carbonate; wherein the catalyst is at least one selected from the complexes formed from multidentate ligand and zinc; wherein the multidentate ligand comprises triphenylphosphine-based compound and salicylic acid-based compound; a molar ratio of the zinc, the triphenylphosphine-based compound and the salicylic acid-based compound in the catalyst is any ratio in a range of 5:1-50: 1-50. The beneficial effects achieved are as follows: the method adopts a complex catalyst system formed from multidentate ligand and zinc. The catalyst achieved 99.8% conversion efficiency of alkylene oxide, 99.5% selectivity of alkylene carbonate, and thus achieved good technical effect. |
