标题 :Three-step synthesis of CL-20
发明人：WRIGHT MICHAEL E
权利人:US NAVY
摘要:Embodiments of the invention relate to the synthesis of CL-20 using only a three step synthesis and because of increased catalyst activity and lifetimes, a continuous flow process can be used with a tremendous reduction in total cost of producing CL-20.

标题:Process for the 2-stage synthesis of hexanitrohexaazaisowurtzitane starting from a primary amine
发明人：CAGNON GUY; ECK GENEVIEVE; HERVE GREGOIRE; JACOB GUY
权利人:SNPE MATERIAUX ENERGETIQUES
摘要: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. n This process comprises a first stage of reaction of an α,β-dicarbonyl derivative with a primary amine which makes it possible to form a hexasubstituted hexaazaisowurtzitane derivative. n The HNIW is subsequently obtained directly, in a single reaction stage, by nitration of the hexasubstituted hexaazaisowurtzitane derivative. n This process, in only 2 stages starting from a primary amine, is particularly simple and inexpensive.
