Claims
- 1. In an improved method of producing improved alpha 1,3,5,7-tetranitro-1,3,5,7-tetrazacyclooctane (HMX), which is pure alpha HMX having a particle distribution between about 1 and about 5 microns thereby producing a highly insensitive alpha HMX for use as a conventional high energetic compound, the improvement consisting essentially of adding HMX contaminated with 1-Aceto-3,5,7-trinitro-1,3,5,7-tetraazacyclooctane to a nitric acid and phosphoric pentoxide solution to facilitate mixing thereby producing a paste, allowing said paste to stand at about 22.degree. to 45.degree. C. degrees Centigrade for at least 16 hours, dispersing said paste in water, filtering, and washing until the pH remains constant, and finally boiling at about 100 to 102 degrees Centigrade said HMX in about 8 times its weight of water to remove residual contamination indicated by the disappearance of any foam.
- 2. The method of claim 1 wherein said paste is a mass maintained by agitation at about 40 to 45 degrees Centigrade throughout said mass thereby ungrading said alpha HMX in about 30 minutes to 4 hours.
- 3. The method of claim 2 wherein said paste is then rapidly mixed, and said temperature is further allowed to rise to about 45 degrees Centigrade thereby reducing said alpha HMX upgrading to 30 minutes.
