What is 4,4'-DIAMINOBIPHENYL-3,3'-DICARBOXYLIC ACID?
Production Methods
Benzidine-3,3' -dicarboxylic acid is made by reducing 2-nitrobenzoic acid with zinc dust and sodium hydroxide solution. The resultant hydrazobenzene-2,2' -dicarboxylic acid is rearranged by heating with hydrochloric acid. The free benzidine-3,3' -dicarboxylic acid is precipitated from the hydrochloric acid solution by adding ammonia or sodium acetate. Electrolytic reduction followed by rearrangement with dilute sulfuric acid is also possible
Safety Profile
Questionable carcinogen withexperimental tumorigenic data. Mutation data reported.When heated to decomposition it emits toxic fumes ofNOx.
