Espinoza, Edgard O’N. published the artcileCharacterization of smokeless gunpowder by means of diphenylamine stabilizer and its nitrated derivatives, Application In Synthesis of 1821-27-8, the publication is Analytica Chimica Acta (1994), 288(1-2), 57-69, database is CAplus.
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 chromatog. and liquid chromatog.
