CHEMICAL TRANSFORMATIONS OF DIPHENYLAMINE DURING THE ACCELERATED DEGRADATION OF SINGLE-BASE GUN PROPELLANTS
Filipović Miloš Jelisavac Ljiljana The test procedure and the optimal conditions of the Reversed-Phase High Performance Liquid Chromatography (RP-HPLC), which permits quantita-tive determination of diphenylamine (DPA) and its mono-derivatives content until their levels fall below limits of detection in single-base gun propellants, was defined. The measuring confidence intervals are determined and it was concluded that the test procedure is precise and the results are reproductive. Using the RP-HPLC method, the chemical transformations of diphenylamine during the accelerated degradation (artificial aging) of the single-base… Ključne reči: high performance liquid chromatography, propellants, chemical stability, diphenylamine, chemical transformations of diphenylamine, derivatives of diphenylamine. |
