2-Nitrodiphenylamine Uses
2-Nitrodiphenylamine(119-75-5) is used as a stabilizer for synthetic rubbers, explosives, propellants (eg. in Otto fuel II, smokeless powders, in some US Army double-base propellants in solid rockets, and in other applications involving nitric acid esters), plastics, and lubricants. It is also an intermediate for organic synthesis, and a civilian solvent dye.
In some explosives, it is used to control the explosion. One of its major uses is to control the explosion rate of propylene glycol dinitrate.
As a stabilizer, its major role is to eliminate the acidic nitrates and nitrogen oxides produced by gradual decomposition of nitric acid esters, which would otherwise autocatalyze further decomposition. Its amount is usually 1-2% of the mixture; higher amounts than 2% degrade the propellant's ballistic properties. The amount of the stabilizer depletes with time; remaining content of less than 0.5% (with initial 2% content) requires increased surveillance of the munition, with less than 0.2% warranting immediate disposal, as the depletion of the stabilizer may lead to autoignition of the propellant.
