3,3′,4,4′-Biphenyltetracarboxylic dianhydride Use and Manufacturing
Into a 300 mL three-neck flask were added 10.0 g of 3, 3′, 4, 4′-biphenyltetracarboxylic acid and the solvent made up of 20 mL of N, N-dimethylacetamide, 100 mL of chlorobenzene, and 40 mL of toluene at room temperature in a nitrogen flow. After being heated up to 111° C., the materials in the flask were subjected to a reaction with stirring at that temperature for 20 hours. After the solvent was removed, the reaction product was washed by being dispersed in toluene and then filtered to yield 5.1 g of 3, 3′, 4, 4′-biphenyltetracarboxylic acid dianhydride.
3,3',4,4'-biphenyltetracarboxylic dianhydride be used for the preparation of a polyimide material.
