| titleOfInvention | Method for preparing annular carbonates through catalyzing by chemical supported polyhydroxy quaternary ammonium ionic liquid |
| abstract | The invention relates to a method for preparing annular carbonates through catalyzing by a supported ionic liquid. The method is characterized in that corresponding annular carbonates are synthesized by catalyzing the cycloaddition of an epoxy compound and carbon dioxide with a chemical supported polyhydroxy quaternary ammonium ionic liquid as a catalyst under conditions that the reaction pressure is 0.5-5.0MPa, the reaction temperature is 50-150DEG C and the reaction time is 1-20h, wherein the catalyst accounts for 0.2-3mol% of the epoxy compound (the content of the catalyst is calculated by the content of the ionic liquid). The synthetic method has the characteristics of high activity, low cost and long service life of the catalyst, easy product separation, easy catalyst recovery and the like, and many hydroxy groups in the molecule of the ionic liquid have an epoxy compound ring-opening induction reinforcing effect. |
