General Description

4-Nitrodiphenylamine undergoes heterogeneous catalytic transfer hydrogenation to form p-phenylenediamines. 4-Nitrodiphenylamine is used as stabilizer for propellants and explosives.

Purification Methods

Crystallise the amine from EtOH or aqueous EtOH (m 135-136o) and has m 131.5-132o after sublimation in vacuo. [Beilstein 12 H 715, 12 III 1586.]
