Abstract
An apparatus and method for continuously producing a cyclic carbonate which are easily scaled up without requiring a large-sized reactor or excessive ancillary facilities even in the case of producing a cyclic carbonate by using an immobilized catalyst as a catalyst on an industrial scale, are able to produce a cyclic carbonate without impairing the expected catalytic efficiency and catalyst lifetime, are economical, and exhibit excellent industrial productivity. The apparatus includes an adiabatic reactor to be filled with a heterogeneous catalyst for reacting an epoxide with carbon dioxide, a circulation path for returning at least a portion of a fluid mixture in a liquid form flowed out through a reactor outlet into the reactor, a carbon dioxide supply means for continuously supplying carbon dioxide in a liquid form or a supercritical state into the circulation path, and an epoxide supply means.
