Smokeless gunpowder frequently contains diphenylamine as a stabilizer. The diphenylamine acts as a nitrate scavenger and in turn is nitrated by complex processes. The various nitrated congeners of diphenylamine, which are numerous, may serve to characterize a sample of gunpowder because these derivatives reflect not only the production of the gunpowder, but also its storage' career and thermal history following manufacture. These derivatives of diphenylamine may be isolated and identified by means of thin-layer chromatography and liquid chromatography. |
