Compared with the preparation of 3,4 '-BPDA from dimethyl phthalate or mixed dimethyl phthalate, this route does not involve the hydrolysis of esters and the separation of isomers, so separation and environmental protection have Very obvious advantages, while the synthesis route is simpler. 2,3,3',4'-BiphenyLtetracarboxylic is also named as α-BPDA;(4,5'-Biisobenzofuran)-1,1',3,3'-tetrone. 2,3,3',4'-BiphenyLtetracarboxylic has been supplying from UCHEM in large quantity with competitive price.
