4,4'-DIAMINOBIPHENYL-3,3'-DICARBOXYLIC ACID Chemical Properties,Uses,Production

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.
