Production of cyclic carbonate

The purpose of the present invention is to provide a practical method for producing a cyclic carbonate, which is widely used for various applications such as electrolytic solutions for lithium-ion secondary batteries and plastic materials, by a reaction between an epoxide (oxirane) and carbon dioxide, the method giving consideration to the reduction of environmental loads and making it possible to produce said cyclic carbonate with high yield under mild conditions, such as at room temperature and atmospheric pressure. The present invention relates to a method for producing a cyclic carbonate, the method being characterized by reacting an epoxide and carbon dioxide in the presence of an iodine-anion-containing phosphonium salt including a hydrogen atom that can form a hydrogen bond with an oxygen atom in the epoxide.
