Del Campo, Pilar published the artcileThin-layer chromatographic stability determination of powder containing diphenylamine as a stabilizer, COA of Formula: C12H9N3O4, the publication is Ion (Madrid) (1975), 35(410), 633-41, database is CAplus.
Thin-layer chromatog. (TLC) provides high reliability in determining the remaining life of a propellant at a given time. By means of a “stabilogram” and with only 1 TLC plate, it is possible to visualize the actual state of the propellant and its resistance to forced aging. 13 Different kinds of propellant, double or single base, were subjected to different aging temperatures and time intervals and examined by traditional (Me violet paper) and TLC methods. The more accurate TLC method is carried out on silica gel G precoated plates and eluted with C6H6. Visualization is by alc. NaOH or by the Mouraour reagent, or without reagents. Colors and Rf of the different dinitro- and trinitro- derivatives of diphenylamine are given.
