  • Gas anti-solvent recrystallization and application for the separation and subsequent processing of RDX and HMX
    Patent number: 5389263
    Abstract: Disclosed is a process for recrystallizing materials that are ordinarily difficult-to-comminute. The process utilizes supercritical fluids and gasses at conditions near their respective vapor pressures which have the ability to dissolve in and expand liquid solutions. The process has been shown to be particularly effective at separating HMX and RDX thereby resulting in a precipitate of RDX which is essentially free of HMX.
