ABSTRACT:
Ammonium picrate, Explosive "D", is converted to picric acid, which is then converted to triaminophenol by the conversion of the aromatic nitro groups to amino groups. The triaminophenols are then converted to triaminobenzenes by the removal of the hydroxyl groups and the triaminobenzenes are converted to m-phenylenediamine, aniline, and primary aliphatic amines by the removal of amino groups.
