Method for preparing biphenyldianhydride isomer by ultrasonic-assisted catalytic coupling

The invention discloses a method for preparing biphenyldianhydride isomers through ultrasonic-assisted catalytic coupling. The main contents include a mixture of a nickel salt catalyst and zinc as a reducing agent, 2-THF used as a solvent, an aryl (or methyl) N - chloronaphthalimide and -4 - propyl (or isopropyl) N - chlorodifluoroimide, under -3 - by means of an ultrasonic-assisted catalytic coupling reaction 60 - 100 °C 0.5 - 3 hours. The separation and purification of the three biphenyltetracarboxylic acid isomers are realized by using different solubility parameters, and the biphenyldianhydride isomer pure product is finally obtained. The invention is characterized in that a simple method for separating the three biphenyltetracarboxylic acid isomers is established, the problem of difficulty in separation of the three biphenyl dianhydride mixtures is solved, and 3,4 - biphenyl dianhydride ’ with an asymmetric structure is obtained at lower cost.

Process for production of 2, 3, 3', 4'-biphenyltetracarboxylic dianhydride

A process for producing 2,3,3′,4′-biphenyltetracarboxylic dianhydride (a-BPDA), comprising dehydrating 2,3,3′,4′-biphenyltetracarboxylic acid in an inert gas atmosphere under heating at 180 to 195° C is disclosed. This process produces high-purity a-BPDA which is suitable for production of a polyimide.
