ABSTRACT:
Method of directly precipitating substantially pure beta HMX from a substantially anhydrous nitric acid solution without forming and recrystallizing polymorphic HMX. HMX dissolved in a solvent consisting essentially of anhydrous nitric acid is added to water which is seeded with crystals of beta HMX to substantially completely precipitate all the HMX from solution as beta HMX without forming crystals of the other polymorphic forms of HMX. A preferred reaction and apparatus for preparing HMX in anhydrous nitric acid is also disclosed.
