摘要:
Provided is a method for continuously producing a cyclic carbonate, by which generation of a glycol in a reaction for synthesizing a cyclic carbonate is suppressed, and a cyclic carbonate having a high purity can be efficiently obtained even by simple purification.
A method for continuously producing a cyclic carbonate, including filling a catalyst in a fixed-bed tube reactor, and continuously feeding carbon dioxide and an epoxide to the fixed-bed tube reactor to thereby bringing the carbon dioxide and the epoxide into contact with the catalyst, while continuously withdrawing the reaction liquid in the fixed-bed tube reactor, wherein the method includes a pre-treatment step in which a pre-treatment liquid containing a cyclic carbonate is brought into contact with the catalyst before feeding the carbon dioxide and the epoxide to the fixed-bed tube reactor, and the generated glycol is removed out of the system.
