Supercrit. fluid extn. (SFE) with CO2 was used for safety evaluations of different propellant formulations based on nitrocellulose, ammonium perchlorate, or RDX. The SFE-technique for sample prepn. from these mixts. of explosives with polymers and plasticizers was compared to conventional Soxhlet extns. SFE was a rapid and environmentally friendly method to study the shelf life and migration phenomenons of additives in solid propellants. The SFE-method took very short extn. times, needed no application of hazardous chlorinated solvents, and the exts. could be analyzed chromatog. without further work-up.
