Abstract Recovery of explosives from obsolete ammunition has been considered an eco-friendly alternative to conventional dumping or detonation disposal methods Composition B, made of 2,4,6-trinitrotoluene (TNT), hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX), and paraffin… Click to show full abstract

Abstract Recovery of explosives from obsolete ammunition has been considered an eco-friendly alternative to conventional dumping or detonation disposal methods Composition B, made of 2,4,6-trinitrotoluene (TNT), hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX), and paraffin wax, has been used as the main explosive filling in various munitions. It was selected as a model explosive for this study. TNT was extracted from Composition B by exploiting the different solubilities of TNT and RDX in acetonitrile. After removing paraffin wax by hexane washing, RDX was recovered from unused Composition B with a purity higher than 99% and a yield of 84%.
