Kurşun İçermeyen Yeni Nesil Primer Patlayıcı Tasarımı, Sentezi ve Karakterizasyonu

Mercury fulminate, lead azide and lead styphnate have been used as primary explosives for a long time. They are very good initiatory explosives, however, they have some serious drawbacks such as thermal, hydrolytic, chemical instability, highly sensitive to light, high toxicity of the compounds themselves, high sensitivity to mechanical stimuli. Today, improvement on the existing primary explosives is essential to find materials without heavy metals with safer production line and more efficient use compared to the present ones. The main aim of this study is to synthesize and explore the initiating performance of novel energetic organic and metallic compounds, which lead to providing the similar or even better performance with lower toxicity. For this purpose, 5-(kloronitrometil)-4-nitro-1H-imidazol ligand and its cobalt, copper, iron and zinc complexes in different geometries were synthesized. The characterization of the complexes was elucidated by elemental analysis, ESI-MS, IR and 1H-NMR spectroscopy techniques. The geometric and electronic properties of the complexes were determined using gas phase density functional theory calculations. Then, the explosive properties of the energetic materials obtained were studied with theoretical methods. The thermal stability of the materials was investigated by TG-TA methods. Explosion safety tests of the two most suitable complexes having exothermic energy profile were completed in the form of service procurement. The results obtained showed that the prepared complexes have very high thermal stability, they do not show the ability to be a primary explosive. However, the complexes having exothermic properties can be used as propelling power, and the complexes having endothermic properties can be used as additives to increase thermal stability against impact and friction in high energy rocket fuels.
