    摘要: 1-Methyl-2,4,5-Trinitroimidazole is synthesized starting from 4-nitroimidazole using stepwise nitration method and further methylation using Dimethylsulphate. It is relatively insensitive to impact and its thermal stability is excellent. The calculated detonation properties indicate that its performance is about 30% better than TATB. It can be prepared easily, with reasonable yield, starting from commercially available Imidazole. Results from impact sensitivity, friction sensitivity, time-to-explosion temperature and vacuum stability tests indicate that it is less sensitive than both RDX and HMX. The good oxygen balance and measured heat of formation data of this material indicate that its propellant performance should be good.

    摘要: A method for synthesizing pentanitrohexaazaisowurtzintane under neutral reaction conditions. Which synthesis involves treating a solution of hexanitrohexaazaisowurtzitane in ethyl acetate in the presence of a catalytic quantity of palladium on a carbon substrate, until a heterogeneous mixture is formed. This heterogeneous mixture is hydrogenated under a balloon atmosphere until the starting hexanitrohexaazaisowurtzitane is substantially reacted. The resulting pentanitrohexaazaisowurzitane mixture is filtered, dried and recovered from the dried residue through a Si-gel column.

    摘要: A method of adjusting the yield of a manufactured compound comprising primarily two energetic materials to yield a product comprising primarily one of the two energetic materials. Specifically, embodiments of the present invention provide a method of purifying a compound primarily comprising RDX and HMX to achieve a desired purity of RDX with an acceptable yield percentage. By adding sufficient acetonitrile (ACN) to the manufactured compound to dissolve it and form a solution; adding a pre-specified volume of water to the resultant solution and stirring sufficiently to precipitate at least the RDX; separating and drying the precipitate, a pre-specified purity and yield percentage of RDX may be obtained by varying the volume of water added. The process uses relatively environmentally benign recyclable solvents at ambient temperature and pressure reducing both environmental impact and energy costs.
