  A manufacturing method for polycarbonate comprising [I] a process for manufacturing diaryl carbonate from an aromatic hydroxy compound and an aromatic hydroxy compound, [II] a process for manufacturing polycarbonate by solution polymerization of the diaryl carbonate obtained in [II] and an aromatic dihydroxy compound in the presence of a catalyst comprising a nitrogen-containing basic compound, and [III] a process for separating and removing the nitrogen-containing compound from the aromatic hydroxy by-products in [II] and returning the resultant aromatic hydroxy compounds to process [I] effectively reuses aromatic hydroxy by-products (e.g., phenols) of polycarbonate manufacturing to manufacture diaryl carbonate, while suppressing the production of alkyl aromatic ethers and then uses this diaryl carbonate to manufacture polycarbonate with good productivity.

  一种聚碳酸酯的制造方法，包括[I]用芳香族羟基化合物和芳香族羟基化合物制造碳酸二芳基酯的工艺，[II]在由含氮碱性化合物组成的催化剂存在下，通过溶液聚合[II]中得到的碳酸二芳基酯和芳香族二羟基化合物制造聚碳酸酯的工艺、和[III]一种从[II]中的芳香族羟基副产物中分离和除去含氮化合物并将所得芳香族羟基化合物返回工艺[I]的工艺，该工艺可有效地再利用芳香族羟基副产物（如......）。g.,酚）来生产碳酸二芳基酯，同时抑制烷基芳香醚的生产，然后利用碳酸二芳基酯生产聚碳酸酯，生产率高。

  To provide a method by which aromatic carbonates can be efficiently manufactured from dialkyl carbonate and an aromatic hydroxy compound with little production of alkyl aromatic ether by-product. Manufacturing method for aromatic carbonates in which dialkyl carbonate and an aromatic hydroxy compound are reacted in the presence of a catalyst under the following conditions: (1) the catalyst used has a specified catalytic activity, (2) values are selected from within specified ranges for amount of catalyst used c, reaction time r, ratio d of raw materials in the reaction system, and reaction temperature t, (3) these values satisfy the relations g(r,t) ≤ 2 and f(c,r,t,d) ≥ 0.02, and (4) the selectivity for alkyl aromatic ethers is less than 1 percent, based on the amount of aromatic hydroxy compound fed to the reaction. Hereinabove, g(r,t,) = (r) ×exp[36-17 ×1000/(273 + t)}], f(c,r,t,d) = (c)×(r)xexp[36-17×1000/(273 + t)}×d/1 + d)2).

  提供一种方法，通过该方法可有效地用碳酸二烷基酯和一种芳香族羟基化合物制造芳香族碳酸盐，且几乎不产生烷基芳香醚副产品。 芳香族碳酸盐的制造方法，其中碳酸二烷基酯和芳香族羟基化合物在催化剂存在下进行反应，反应条件如下：(1) 所用催化剂具有规定的催化活性；(2) 催化剂用量 c、反应时间 r、反应体系中原料比例 d 和反应温度 t 的值在规定范围内选择；(3) 这些值满足 g(r,t) ≤ 2 和 f(c,r,t,d) ≥ 0.02，以及 (4) 根据加入反应的芳烃羟基化合物的量，烷基芳香醚的选择性小于 1%。 这里，g(r,t,) = (r) ×exp[36-17 ×1000/(273 + t)}]、 f(c,r,t,d) = (c)×(r)xexp[36-17×1000/(273 + t)}×d/1 + d)2)。
