Abstract

DPA and N-NODPA are used to maintain the stability of nitrocellulose propellants. In this paper, we examined the possibility of using High Performance Thin Layer Chromatography (HPTLC) for the qualitative and quantitative determination of DPA and N-NODPA, using a toluene as the carrier solution. 42% of all results showed difference in range up to ±0.01% (±8ng), and the other 58% showed full agreement of results at 254 nm. The results of the HPTLC in comparison with HPLC test have shown that this method can be used in the qualitative and quantitative analysis of single-base propellants, tested on propellants samples of ammunitions calibers of 20, 30, 100, 105, 122 and 125mm. With increasing of [%] DPA and N-NODPA we detected decreasing of released NOx gases from almost all tested calibers. The results obtained by the HPTLC method, in combination with other analytical methods such as the vacuum stability test, can be successfully used to predict the stability of propellants.
