Dynamic supercrit. fluid extn. of PETN, nitroguanidine (NIGU), and RDX, resp., with pure and modified CO2 indicated that all explosives except NIGU were extd. though for RDX and 3-nitro-1,2,4-triazole the use of modifiers proved to be necessary. The results show the high capacity of modified supercrit. CO2 as a solvent in RESS- and GAS-processes.en660662journal article
