  The present invention provides a salicylic acid ester derivative having an impurity content lower than a specific level and expressed by the following formula (1) (in the formula, R1 is methyl group or ethyl group, R2, which may be substituted optionally, is an alkyl group having a carbon number of from 1 to 30, alkoxy group having a carbon number of from 1 to 30, aryl group having a carbon number of from 6 to 30, aryloxy group having a carbon number of from 6 to 30, aralkyl group having a carbon number of from 6 to 30 or aralkyloxy group having a carbon number of from 6 to 30). The salicylic acid ester derivative is effective as a terminal blocking agent or a polymerization promoting agent for a polycarbonate, and gives a polycarbonate having good color tone and suitable for optical material use.

  本发明提供一种水杨酸酯衍生物，其杂质含量低于特定水平，用下式(1)表示(式中，R1为甲基或乙基，R2可被任选取代，为碳原子数为1至30的烷基、碳原子数为1至30的烷氧基、碳原子数为6至30的芳基、碳原子数为6至30的芳氧基、碳原子数为6至30的芳烷基、碳原子数为6至30的芳烷基)、碳原子数为 1 至 30 的烷氧基、碳原子数为 6 至 30 的芳基、碳原子数为 6 至 30 的芳氧基、碳原子数为 6 至 30 的烷基或碳原子数为 6 至 30 的烷氧基）。水杨酸酯衍生物可有效用作聚碳酸酯的末端封端剂或聚合促进剂，并可得到具有良好色调且适合光学材料使用的聚碳酸酯。

  An aromatic polycarbonate and an active-hydrogen compound are subjected to the transesterification reaction in the presence of a transesterification catalyst under a reduced pressure condition followed by reaction with a salicylic acid ester derivative expressed by the following chemical formula (1), wherein X is methyl or ethyl, and Y is a carbonyl group or a divalent functional group expressed by the following formula (2), (where Z is an alkylene group having a carbon number of 1 to 30, an arylene group having a carbon number of 6 to 30 or an aralkylene group having a carbon number of 7 to 30)}. An aromatic polycarbonate having a high molecular weight can be produced by this process.

  芳香族聚碳酸酯和活性氢化合物在减压条件下，在酯交换催化剂存在下进行酯交换反应，然后与下式(1)表示的水杨酸酯衍生物反应、 其中 X 是甲基或乙基，Y 是羰基或下式（2）表示的二价官能团、 (其中 Z 是碳原子数为 1 至 30 的亚烷基、碳原子数为 6 至 30 的芳烷基或碳原子数为 7 至 30 的芳烷基）}。 通过该工艺可生产出具有高分子量的芳香族聚碳酸酯。
