Abstract: Disclosed is a process for producing an aromatic carbonate which comprises reacting a phenolic compound with a di-aliphatic carbonate or an aliphatic-aromatic carbonate in the presence of a catalyst. The catalyst is either SnO and/or a tin compound represented by the following formula wherein X and Y are identical or different and each represents OH, SCN, OR , OCOR or a halogen atom, R represents an alkyl or aryl group, X and Y are not alkoxy groups at the same time, and R represents an alkyl or aryl group; or at least one compound of an element selected from the group consisting of Sc, Cr, Mo, W, Mn, Au, Ga, In, Bi, Te and lantanoids. The use of these specific catalysts enables the product to be obtained in high yields and selectivities and makes it easy to purify the product.

Abstract: Cyclic carbonates are prepared by reacting a 1,3diol or 1,2-diol with a dialkylcarbonate in the presence of a basic catalyst. They are obtained in higher yields with higher purity by subjecting the reaction mixture to heat aging under vacuum in the presence of the basic catalyst, and recovering the cyclic carbonate from the mixture.
