The synthesis of novel energetic salts based of N-(1-carboxymethyl-1H-tetrazol-5-yl)-hydrazinium

摘要

One of the overall goals of energetic materials, synthesis of materials with acceptable performance and low sensitivity to physical stimuli. Since the creation of networks of hydrogen bonds, good stability of the triggers may be created and on the other hand azole-based ion high-energy materials (especially aminotetrazole) and other nitrogen-rich compounds that have a strong hydrogen bonds, Significant stability and insensitivity to physical stimulus and also have a good performance. The nitrogen rich compounds are often different from conventional explosives such as TNT, TEX, CL-20 and HMX. The energy of nitrogen rich compounds are obtained from the high positive heat of formation (?H_f), while the second category of energy from the oxidation of their carbon body and the pressure cage. Studies have shown that the incorporation of hydrazino groups into a tetrazole ring will increase the heat of formation of the molecule and increase hydrogen bonds, which decreases sensitivity to physical stimuli. Also nitroiminotetrazole and their derivatives suitable for high explosives because they combine both the strongly oxidizing and the energetic nitrogen-rich backbone in one molecule, this combination produced a very simple, safe and is inexpensive. Hence, the industry is very important. In this study after the Synthesis salt of N-(1-Carboxymethyl-1H-tetrazol-5-yl)-hydrazinium chloride, the reaction of anion exchange of chlorine with nitrate, 5-aminotetrazolate, (5-Amino-tetrazol-1-yl)-acetate and (5-nitroiminotetrazole-1-yl)-acetate and formation AgCl precipitate, salts to be synthesized and analysis of all products produced using ~1H NMR,~(13)C NMR, IR and UV-Vis identified and verified, among the advantages of this study, the use of methods and equipment available and low-risk solvents during the reaction and achieve at least the byproducts of the process took place.
