METHOD FOR SYNTHESIZING CYCLIC CARBONATES

摘要

Disclosed is a method for synthesizing cyclic carbonates, wherein a compound as represented by formula (I) or formula (II) is used as the catalyst, wherein R1 is methyl or ethyl; R2 is a C10-18 alkyl group; X- is one of Cl-, Br-, I-, BF4 - and PF6 -, and Y- is one of Cl-, Br-, I-, BF4 -, PF6 -, CH3SO3 - and CH3C6H4SO3 -. No organic solvent or cocatalyst is used in the reaction process. The reaction temperature is 50 to 140°C, the reaction time is 1 to 24 hours, the reaction pressure is 0.1 to 0.5 MPa, and the molar ratio of the substrate to the catalyst is in the range of 1000:1 to 50:1. Compared to the traditional synthesis methods, the method disclosed has the advantages of being simple in processes, environmentally-friendly, mild in conditions, high in catalyst activity, high in efficiency, low in energy consumption and free of equipment corrosion.
