  A diaryl carbonate with a high degree of purity is produced at a high yield by (A) subjecting (a) a diaryl oxalate and a phenol compound or (b) an alkylaryl oxalate to transesterification reaction in one or two stages in the presence of a catalyst to prepare a diaryl oxalate, while removing a by-product from the reaction system; (B) collecting the diaryl oxalate from the resultant reaction product mixture of the step (A); (C) subjecting the diaryl oxalate to a decarbonylation reaction, preferably in the presence of a phosphorous compound-containing catalyst, to convert the diaryl oxalate to a corresponding diaryl carbonate, while removing a reaction by-product comprising carbon monoxide from the reaction system; and (D) collecting the diaryl carbonate from the reaction product mixture of the step (C).

  高纯度碳酸二芳基酯的制备方法是：(A)在催化剂存在下，将(a)草酸二芳基酯和苯酚化合物或(b)草酸烷基芳基酯在一个或两个阶段中进行酯交换反应，制备草酸二芳基酯，同时从反应体系中除去副产物；(B)从步骤(A)的反应产物混合物中收集草酸二芳基酯；(C) 将草酸二芳基酯进行脱羰基反应，最好是在含磷化合物催化剂存在下进行，以将草酸二芳基酯转化为相应的碳酸二芳基酯，同时从反应体系中除去由一氧化碳组成的反应副产物；以及 (D) 从步骤(C)的反应产物混合物中收集碳酸二芳基酯。
