4,4'-DIAMINOBIPHENYL-2,2'-DICARBOXYLIC ACID Usage And Synthesis

Production Methods

Benzidine-2,20 -dicarboxylic acid (4,4' -diaminobiphenyl-2,2' -dicarboxylic acid) is made from 3-nitrobenzoic acid by reduction with zinc dust and sodium hydroxide solution to form the hydrazo compound. This is followed by rearrangement using hydrochloric acid to form the dihydrochloride.
