Regarding the chromatographic analysis of the stabilizers in the double based propellants, nitrocellulose causes an interference problem with diphenylamine and its derivatives. In this study, specific extraction of the stabilizer was planned before the chromatographic analysis and the stabilizer was extracted into CHCl3 by means of a soxhylet extraction in order to eliminate this problem. Then, most of the CHCl3 was evaporated under hydrothermal conditions and the residue was analyzed with HPLC after being dissolved in MeCN. By means of an isocratic work, the stabilizer 2-nitro diphenylamine (2NDPA) was clearly detected with 85% MeCN and 15% H2O carrier phase in CI8 column. The effect of the matrix that could be found in the ambient was examined and the recovery was found between 95.06 +/- 3.09 - 99.88 +/- 3.34%. No matrix effect was determined in the ambient.
