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, OR¹, OCOR¹ or a halogen atom, R¹ 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.
本发明公开了一种生产芳香族碳酸盐的工艺,该工艺包括在催化剂存在下使酚类化合物与二脂肪族碳酸盐或脂肪族-芳香族碳酸盐反应。催化剂为氧化锡和/或由下式表示的锡化合物
其中 X 和 Y 相同或不同,各自代表 OH、SCN、OR¹、OCOR¹ 或卤素原子,R¹ 代表烷基或芳基,X 和 Y 同时不是烷氧基,R 代表烷基或芳基;或至少一种选自 Sc、Cr、Mo、W、Mn、Au、Ga、In、Bi、Te 和 lantanoids 的元素化合物。使用这些特定的催化剂,可以获得高产率和高选择性的产品,并使产品易于纯化。
