Sopranetti, A. published the artcileSimultaneous analysis of stabilizers and their decomposition products by gas chromatography – application of the new methods for the judging of propellants by the 65.5.degree.C surveillance test, Product Details of C12H9N3O4, the publication is Symposium on Chemical Problems Connected with the Stability of Explosives, [Proceedings] (1977), 73-98, database is CAplus.

Gas chromatog. (GC) is not able to sep. PH2NH (I) [122-39-4] and Ph2NNO (II) [86-30-6] in I-stabilized propellants because II is thermally unstable and is converted partially or wholly to I. An acylation product of I (with heptafluorobutyric acid anhydride) is easily synthesized at ambient temperature and has high thermal and hydrolytic stability. Moreover, the retention time of this compound is shorter than that of I and its nitration products. Thus, in GC the acylized I appears as the first peak, followed by II, which decomposed into I, and then the further nitrated I. I and its consecutive products are isolated from propellant grains by mech. crushing with no heat to a particle size <0.25 mm., followed by extraction by stirring at ambient temperature with CH2Cl2. The transformation rate of I and the formation of its consecutive products in propellants subjected to the 65.5.degree. heat test can be checked by GC. When dealing with propellants of comparable composition, the safe life can now be judged after 60 day storage.
