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:
Processes and compositions for nitration of N-substituted isowurtzitane compounds with concentrated nitric acid at elevated temperatures to form HNIW and recovery thereof with high yields and purities. Polymorphic conversions to the epsilon HNIW crystal form at quanititative yields are also described.
