Nitrogen-rich 5,5′-bistetrazolates and their potential use in propellant systems: A comprehensive study

A large variety of twice-deprotonated nitrogen-rich 5,5′- bistetrazolates, that is, the ammonium (1), hydrazinium (2), hydroxylammonium (3), guanidinium (4), aminoguanidinium (5), diaminoguanidinium (6), triaminoguanidinium (7), and diaminouronium (8) salts, have been synthesized. Energetic compounds 1-8 were fully characterized by single-crystal X-ray diffraction (except 8), NMR spectroscopy, IR and Raman spectroscopy, and differential scanning calorimetry (DSC) measurements. With respect to their potential use in propellant applications, the sensitivity towards impact, friction, and electrical discharge were determined. Several propulsion and detonation parameters (e.g., heat of explosion, detonation velocity) were computed by using the EXPLO5 computer code based on calculated (CBS-4M) heats of formation and X-ray densities. Additionally, the performance of 1-8 in various formulations was investigated by calculating the specific energy and specific impulse of the compounds under isochoric conditions. The thrust generation: The synthesis and complete characterization of a series of nitrogen-rich salts of 5,5′-bistetrazole gave promising materials with potential applications in novel propellant systems (see figure). In addition to their good thermal and chemical stability, the high nitrogen content leads to good N2/CO ratios when combusted, which is desirable to avoid environmental and corrosion problems.

Process for the preparation of 5,5'-bi-1H-tetrazole salt

A process for the preparation of a 5,5'-bi-1H-tetrazole diammonium salt by dropwisely adding the aqueous hydrogen peroxide to which a small amount of weakly acidic substance has been added, to a starting aqueous solution containing hydrogen cyanide or sodium cyanide or potassium cyanide, sodium azide and a catalytic amount of copper sulfate preferably at a low temperature to maintain the pH of the reaction solution over a range of from 5 to 6, heating the reaction solution to effect the oxidation and cyclization reaction, reacting the reaction product with ammonium chloride or an aqueous solution thereof, and recovering the formed ammonium salt in the form of sparingly soluble crystals. The desired product is obtained in a high yield and in a high purity from the starting materials which are cheaply available and are easy to handle through a decreased number of steps, i.e., through a one-pot reaction without requiring cumbersome after-treatment.
