  Disclosed is a process for preparing a diaryl oxalate which comprises the step of transesterifying a dialkyl oxalate or/and an alkylaryl oxalate with an aryl alcohol in the presence of a tetra(aryloxy)titanium as a catalyst, wherein the tetra(aryloxy)titanium is fed into a reaction system of the transesterification as an aryl alcohol solution of the tetra(aryloxy)titanium which is prepared by reacting a tetraalkoxy titanium and an excess amount of the aryl alcohol and removing a by-producing alkyl alcohol.

  揭示了一种制备二芳基草酸酯的方法，包括在四(芳氧基)钛存在下，通过将二烷基草酸酯和/或烷基芳基草酸酯与芳基醇进行酯交换的步骤，其中四(芳氧基)钛以芳基醇溶液的形式加入酯交换的反应系统中，该芳基醇溶液是通过将四烷氧基钛和过量的芳基醇反应制备的，并去除生成的副产物烷基醇。

  A catalyst composed of an organic phosphorus compound having a trivalent or pentavalent phosphorus atom and at least one carbon-phosphorus bonding or a combination of the organic phosphorus compound and a halogen atom-containing compound is effective for decarbonylation, that is, for releasing carbon monoxide from a compound containing a moiety of -CO-CO-O- in its molecular structure.

  一种由含有三价或五价磷原子的有机磷化合物和至少一个碳-磷键合或有机磷化合物与含卤原子的化合物的组合构成的催化剂对于脱羰基作用是有效的，即从含有分子结构中的-CO-CO-O-基团的化合物中释放一氧化碳。

  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。

  A high purity diaryl carbonate is produced with a high efficiency by reacting carbon monoxide with an alkyl nitrite and/or an alkyl alcohol; reacting the resultant dialkyl oxalate with a hydroxyaryl compound, for example, phenol; decarbonylating the resultant diaryl oxalate to produce a diaryl carbonate and carbon monoxide; and collecting the diaryl carbonate from the decarbonylation reaction product mixture, the carbon monoxide produced in the decabonylation step being optionally reused for the production of the dialkyl oxalate.

  将一氧化碳与亚硝酸烷基酯和/或烷基醇反应；将生成的草酸二烷基酯与羟基芳基化合物（例如苯酚）反应，可高效生产出高纯度碳酸二芳基酯；对生成的草酸二芳基酯进行脱羰基反应，生成碳酸二芳基酯和一氧化碳；从脱羰基反应产物混合物中收集碳酸二芳基酯，脱羰基步骤中生成的一氧化碳可选择重新用于生产草酸二烷基酯。
