| titleOfInvention | Catalyst, preparation and application for the preparation of alkylene carbonate |
| abstract | The invention relates to a catalyst for preparing alkylene carbonate by addition reaction of epoxide and carbon dioxide and a preparation method thereof, and mainly solves the problem of low catalyst activity existing in the prior art. It includes the following steps: mixing cyclic phenol aromatic hydrocarbon, solvent and nitrogen-containing compound or phosphorus-containing compound to obtain the catalyst. The technical scheme of the invention better solves the problem of low catalyst activity in the reaction of benzene alkylene carbonate, and can be used in the industrial production of alkylene carbonate. |
