    Abstract: A cocrystal of CL-20 (2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaazaisowurtzitane) and DNMT (1-methyl-3,5-dinitro-1,2,4-triazole) was formed through a resonant acoustic mixing process. The resulting cocrystal comprised an essentially 1:1 stoichiometric ratio between these coformers. The cocrystal advantageously has decreased sensitivity when compared with a pure CL-20 sample, and maintains thermal stability and comparable energetic performance.

  • Publication number: 20150080567
    Abstract: A method to produce and manufacture cocrystals and salts is disclosed wherein crystalline solids and other components were combined in the desired proportions into a mixing chamber and mixed at high intensity to afford a cocrystalline product. No grinding media were required. The mixing system consists of a resonant acoustic vibratory system capable of supplying a large amount of energy to the mixture and is tunable to a desired resonance frequency and amplitude. The use of resonant acoustic mixing to assist cocrystallization is novel. This discovery enables the manufacture of cocrystals and salt forms, simplifying their manufacture and scale-up, and avoiding the use of grinding methods or grinding media. The present invention affords the manufacture of cocrystals and salts on kilogram to multi-ton scale and is adaptable to continuous manufacturing through the use of resonant mixing methods.
