    • A process for producing an aromatic carbonate, which comprises the steps of: (I) transesterifying a starting material selected from the group consisting of a dialkyl carbonate, an alkyl aryl carbonate and a mixture thereof with a reactant selected from the group consisting of an aromatic monohydroxy compound, an alkyl aryl carbonate and a mixture thereof, in the presence of a catalyst, to thereby obtain a high boiling point reaction mixture comprising an aromatic carbonate (a) and an aromatic carbonate ether (b), while withdrawing a low boiling point reaction mixture containing a low boiling point by-product; and (II) separating the aromatic carbonate ether (b) from the high boiling point reaction mixture to thereby obtain a high purity aromatic carbonate.
    • 一种制备芳族碳酸酯的方法,该方法包括以下步骤:(I)将选自碳酸二烷基酯,碳酸烷基芳基酯及其混合物的原料与选自芳族碳酸酯,芳族碳酸酯,芳族碳酸酯和芳族碳酸酯的反应物进行酯基转移反应, 单羟基化合物,烷基芳基碳酸酯及其混合物在催化剂存在下反应,由此获得包含芳族碳酸酯(a)和芳族碳酸酯醚(b)的高沸点反应混合物,同时提取低沸点 含有低沸点副产物的反应混合物; 和(II)从高沸点反应混合物中分离芳族碳酸酯醚(b),从而获得高纯度芳族碳酸酯。
