The way towards a CL-20/HMX Cocrystal scale-up

A variety of techniques to produce the CL 20/HMX cocrystal have been published, since its discovery in 2012. However, their capability of producing the cocrystal in a size region and production scale suitable for its use in polymer bonded explosives (PBX) has as of yet neither been tried nor assessed. In the corresponding presentation that is based on previously published work (10.1002/prep.201800332) the systematic process of selecting suitable solvents and crystallisation methods as well as optimisation thereof with a focus on the efficient production of high-quality cocrystals for use in PBX is illustrated.
