Because of their specific phys. properties supercrit. fluids show a specific soly. for various org. substances. Esp. carbon dioxide with it's moderate crit. data (Tc = and pc = 7.28 MPa), noninflammability and chem. inertness was found to be an attractive alternative to hazardous org. solvents. Main objective of this work was to study potential applications on supercrit. CO2 in the processing of energetic materials. Generally, the soly. or extractability of energetic materials like TNT, RDX, HMX, PETN and NTO strongly depends on pressure, temp. and specific modifying agents. Presented topics and potential applications of SC-CO2 are: examn. of phase-equil.-data for different concns. of TNT in liq. and SC-CO2 under static conditions using a special designed sample cell; study of extn. efficiencies for TNT-contaminated soil samples as a function of the used extn. conditions and esp. as a function of the soil matrixes (SFE in anal. scale); screening of the extractability of di fferent explosives in SC-CO2 as a function of the used extn. parameters (pressure, temp., time, usage of modifiers) using a dynamical SFE-app. in anal. scale; and examn. of usable processing conditions for the prodn. of explosives like TNT and RDX with small particle sizes.
