| titleOfInvention | A kind of method of support type quaternary alkylphosphonium salt catalyst preparation cyclic carbonate |
| abstract | The present invention relates to a kind of method of support type quaternary alkylphosphonium salt catalyst preparation cyclic carbonate, catalyst is used as using support type quaternary alkylphosphonium salt, catalyst amount is the 0.2 5% of epoxides mole, with three (2,4,6 trimethoxyphenyls) phosphine cubage is 0.3 10Mpa in reaction pressure, reaction temperature is 80 180 DEG C, catalysis epoxidation thing and the corresponding cyclic carbonate of carbon dioxide cycloaddition synthesis under conditions of the reaction time is 0.5 24h.This method has the advantages that preparation condition is gentle, and catalyst activity is high, service life length, and product is easily separated and catalyst easily reclaims. |
