  • Crystallization of 2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaazatetracyclo[5.5.0.05,903,11]-dodecane
    Patent number: 6350871
    Abstract: CL-20 is crystallized from a solution containing a CL-20 organic solvent and a CL-20 non-solvent miscible with the solvent. The CL-20 non-solvent is a nitrate ester, preferably poly(glycidyl nitrate) and/or triethyleneglycol-dinitrate, although other nitrate ester plasticizers having acceptable volatilities and impact sensitivities can be used. The solution is saturated with CL-20, and CL-20 is then crystallized from the saturated solution by adding &egr;-polymorph CL-20 crystalline seeds to the solution and evaporating off the CL-20 solvent, preferably under vacuum. The nitrate ester non-solvent is then separated from the crystalline CL-20, such as by filtration of the CL-20 crystals or by diluting the slurry of non-solvent and CL-20 with an environmentally acceptable solvent that is miscible with the non-solvent but in which the CL-20 is insoluble.
