Biodegradation of the explosive hexahydro-1,3,5-trinitro-1,3,5-triazine RDX occurs under anaerobic conditions to yield a number of products including hexahydro-1-nitroso-3,5-dinitro-1,3,5-triazine, hexahydro-1,3-dinitroso-5-nitro-1,3,5-triazine, hexahydro-1,3,5-trinitroso-1,3,5-triazine, hydrazine, 1,1-dimethylhydrazine, 1,2-dimethylhydrazine, formaldehyde, and methanol. A scheme for the biodegradation is proposed which proceeds via successive reduction of the nitro groups to a point where destabilization and fragmentation of the ring occurs. Th non-cyclic degradation products arise via subsequent reduction and rearrangement reactions of the fragments.
