Conversion of demilitarized TNT to higher value products

The goal of our research is to develop the scientific methodology needed for the chemical conversion of surplus TNT (2,4,6-trinitrotoluene) into higher value products. Although the military use of TNT is well documented, the production of civilian products from TNT is virtually unknown. We now describe some of our results using TNT as a multipurpose raw material for the chemical synthesis of a variety of materials. Specifically, we have developed more ecologically acceptable conversions of TNT into 2,4,6-triaminotoluene (TAT), 2,4,6-trihydroxytoluene and 2,4,6-triisocyanatotoluene (TICT). In addition, we have studied both the regioselective reductions and regioselective nucleophilic displacements of nitro groups in TNT. We have also converted TNT into a variety of heterocyclic compounds. In summary, our investigations demonstrate that TNT is a versatile building block for the synthesis of new materials ranging from polymers to heterocyclic compounds displaying pharmacological and agrochemical activities.
