Abstract: PURPOSE:To provide a reaction solution having lower viscosity and ready handleability and to obtain a cyclic carbonate simply in high yield and in high selectivity in reacting a carbonic acid ester with a diol by using a specific amount of a solvent and carrying out the reaction. CONSTITUTION:In reacting a diol (e.g. 1,3-propanediol or 2-phenyl-1,3- propanediol) with a carbonic acid ester (e.g. dimethyl carbonate, methylphenyl carbonate or diphenyl carbonate) in the presence of a catalyst such as NaOH or BF3, a solvent is used in the range to provide at least one concentration of the diol and the carbonic acid ester with 99-0.0001wt.%, preferably 50-1wt.% to give a cyclic carbonate (e.g. 5,5-dimethyl-1,3-dioxan-2-one). An aromatic hydrocarbon, an aliphatic hydrocarbon, a halogenated hydrocarbon, a nitrated hydrocarbon, an ether or a sulfoxide is especially preferable as the solvent used. The cyclic carbonate is a synthetic raw material for polycarbonate and is convenient for graft polymerization.
