The invention relates to a novel pyridyl ionic liquid, which has any structural formula shown as follows: . The invention also provides a method for synthesizing cyclic carbonate by using the ionic liquid catalyst. The invention solves the problem of the prior utilization of CO 2 The method for synthesizing the cyclic carbonate ester with the epoxy compound has the problems of low catalyst performance, harsh reaction conditions and use of an organic solvent or a cocatalyst, and takes the novel pyridyl ionic liquid as the catalyst to catalyze the epoxy compound and CO at the temperature of 30-90 ℃ and under the pressure of 0.1-0.5 MPa 2 Cycloaddition reaction is carried out to generate cyclic carbonate, and the highest yield can reach 98.1%. |
