Process and compositions for nitration of n-nitric acid at elevated temperatures to form HNIW and recovery of gamma HNIW with high yields and purities and crystallizations to recover epsilon HNIW crystals

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.
