Abstract
A method of manufacturing cyclic carbonate comprises a step of “preparation,” by preparing an ionic liquid polymer; and a step of “cyclization,” by feeding carbon dioxide and epoxide into a reactor containing the ionic liquid polymer to conduct a cyclization of the carbon dioxide and the epoxide in a batch or continuous reaction manner under the catalysis of the ionic liquid polymer, and finally to produce cyclic carbonate.

A method of manufacturing cyclic carbonat comprising:
- a preparation step of preparing and placing an ionic liqiud polymer in a buffer tank, wherein, the ionic liquid polymer is a poly(alkenylimidazlium haloid)) being selected from poly[1-(2-hydroxyl-ethyl)-3-vinylimidazolium bromide], poly(1-vinyl-3-alkyl imidazolium bromide) or poly[1-vinyl-3-(ω-hydroxyl-alkyl) imidazolium bromide];
- and
- a cyclization stop of catalyzing a cyclization reaction carbon dioxide with an epoxide in a batch or continuous reaction manner under the catalysis of the ionic liquid polymer, and finally to produce cyclic carbonate.
