Compatibility of 2, 4, 6, 8, 10,12-Hexanitrohexaazaisowurtzitane with a Selection of Insensitive Explosives

Thermal techniques (differential scanning calorimetry (DSC) and the vacuum stability test (VST)), according to STANAG 4147, and non-thermal techniques (Fourier transform infrared (FTIR) spectrometry and X-ray diffractometry (XRD)) were used to examine compatibility issues for 2,4,6,8,10,12-hexanitrohexaazaisowurtzitane (CL-20) with a selection of insensitive explosives, including nitroguanidine (NQ), 2,4,6-trinitrotoluene (TNT), 2,6-diamino-3,5-dinitropyridine-1-oxide (ANPyO), 2,4,6-triamino-1,3,5-trinitrobenzene (TATB), 3-nitro-1,2,4-triazol-5-one (NTO) and 2,6-diamino-3,5-dinitropyrazine-1-oxide (LLM-105). DSC measurements showed that ANPyO, TATB, NTO and LLM-105 were compatible with CL-20. The compatibility of CL-20/NQ, CL-20/TNT, CL-20/ANPyO, CL-20/TATB, CL-20/NTO and CL-20/LLM-105 mixtures was further explored using the VST, which revealed that all the selected insensitive explosives were compatible with CL-20. Possible chemical interactions were suspected for CL-20/TATB from the FTIR results and for CL-20/NTO from XRD analysis. In summary, ANPyO and LLM-105 demonstrated the optimal compatibility with CL-20.

Abstract

API gravity, sulfur content, gas chromatography, and gas chromatography-mass spectrometry analyses were carried out for eight oil samples collected from different wells in the Gulf of Suez. The results showed that two types of oils could be recognized: (a) heavy oils, which are oils from Zafarana, Rahmi, West Bakr, and Ras Gharib wells, are of low maturation and originated mainly from terrestrial organic sources; and (b) light oils, which are oils from Um El Yuser, Ras El Ush, Gemsa-SE, and Hurghada wells, have a high level of maturation and orginate mainly from marine organic sources.
