Abstract: The present invention relates to a sequential one-pot synthesis of TKX-50, suitable for larger-scale production, during which an acetyl halide is used during the cyclization of diazidoglyoxime so as to obtain 1,1?-diacetyl-5,5?-bistetrazole, which is then hydrolyzed to 5,5?-bistetrazole-1,1?-diolate, to which compound a hydroxylammonium salt is subsequently added.

Abstract: The present invention relates to a process for determining the sensitive or insensitive nature of a crystalline hexogen. Said process comprises: the formulation of said crystalline hexogen in a matrix; the analysis of a sample of said matrix charged with said crystalline hexogen by differential scanning calorimetry; said matrix consisting essentially of at least one liquid polymer that is suitable for the formulation of binders for energetic materials charged with nitro organic explosives; and of at least one adsorbent for the volatile organic compounds, which is stable at the operating temperature of the analysis and which has low affinity for water. The present invention also relates to the crystalline hexogen in such a matrix.

Abstract: A subject-matter of the present invention is a novel process for the synthesis of hexanitrohexaazaisowurtzitane (HNIW), a compound of use as energetic filler in powders, propellants and explosives. This process comprises a first stage of reaction of an ?,?-dicarbonyl derivative with a primary amine which makes it possible to form a hexasubstituted hexaazaisowurtzitane derivative. The HNIW is subsequently obtained directly, in a single reaction stage, by nitration of the hexasubstituted hexaazaisowurtzitane derivative. This process, in only 2 stages starting from a primary amine, is particularly simple and inexpensive.
