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 &agr;,&bgr;-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.
本发明的主题是一种新型合成六硝基六氮杂异戊烷(HNIW)的方法,该化合物可用作粉末、推进剂和炸药中的能量填料。该方法包括第一阶段反应,将α,β-二羰基衍生物与一级胺反应,从而形成六取代六氮杂异戊烷衍生物。随后通过对六取代六氮杂异戊烷衍生物进行硝化反应,直接得到HNIW,整个过程只需一步反应即可完成。该方法只需从一级胺出发,只需两个步骤,非常简单且经济实用。
