A process for producing an aromatic carbonate which comprises: reacting a dialkyl carbonate represented by general formula (1) with an aromatic carboxylic acid aryl ester represented by general formula (2) in the presence of a catalyst to produce an aromatic carbonate represented by one or both of general formulae (3) and (4):
R-OCOO-R (1)
Ar'-COO-Ar (2)
Ar-OCOO-R (3)
Ar-OCOO-Ar (4)
wherein R represents an alkyl group having from 1 to 4 carbon atoms, and Ar and Ar' each represents an unsubstituted phenyl group or a phenyl group substituted by a substituent selected from the group consisting of alkyl, alkoxy, aryl, aryloxy and a halogen atom.
一种生产芳香族碳酸盐的工艺,包括:通式(1)代表的碳酸二烷基酯与通式(2)代表的芳香族羧酸芳基酯在催化剂存在下反应,生成通式(3)和(4)中的一个或两个所代表的芳香族碳酸盐:
R-OCOO-R (1)
Ar'-COO-Ar (2)
Ar-OCOO-R (3)
Ar-OCOO-Ar (4)
其中 R 代表具有 1 至 4 个碳原子的烷基,Ar 和 Ar'分别代表未取代的苯基或被选自烷基、烷氧基、芳基、芳氧基和卤素原子的取代基取代的苯基。
