(652b) Degradation and Transformation Studies of 2,4 -Dinitroanisole (DNAN) On Nanoparticles of Magnesium and Zinc Oxide Nanomaterials

Understanding the degradation and transformation mechanisms and pathways of the new ?Insensitive Munitions' (IM) will foster development of efficient processes for mitigation of Army waste streams prior to introduction of these compounds into service. Residuals from the IM formulations may soon appear in waste streams from industrial facilities and in environmental matrices. It is timely and appropriate to explore novel nanomaterials for their surface functionality and reactivity for degradation of IM compounds and thereby facilitating development of innovative treatment technologies. This presentation focuses on results of studies on synthesis of nanomaterials of magnesium and zinc oxides and degradation studies of one of the insensitive munitions compound 2,4-Dinitroanisole (DNAN). Preliminary results indicate that the primary ring cleavage occurs through hydroxylation of DNAN. Denitration and amination of the DNAN are also observed.
