摘　　要：综述了以联苯四酸二酐为原料之一生产的聚酰亚胺的主要用途,介绍了联苯四酸二酐的三种异构体:3,3',4,4'-联苯四酸二酐、2,2',3,3'-联苯四酸二酐和2,3',3,4'-联苯四酸二酐们的几种合成路线,包括脱卤偶联法,氧化偶联法等。重点讨论了脱卤偶联反应的历程。The application of the biphenyltetracarboxylic dianhydride in the production of polyimide is reviewed. The three isomers of biphenyltetracarboxylic dianhydride are mainly introduced, including 3, 3＇, 4, 4＇ -biphenyltetracarboxylic dianhydride, 2, 2＇, 3, 3＇ -biphenyltetracarboxylic dianhydride and 2, 3＇, 3, 4＇ - biphenyltetracarboxylic dianhydride. Several synthetic methods are discussed, such as dehalogeno-coupled method, oxygenation-coupled method, etc. The process of the dehalogeno-coupled reaction is presented. The catalysis theory is analyzed emphatically concen- trating on the examples of Pd/C and PPh3.
