ABSTRACT:
An environmentally friendly methods for making 2,4,6-trinitrotoluene (TNT) compounds comprising, providing nitromalondialdehydes, providing dinitro-compounds, reacting the nitromalondialdehydes with the dinitro-compounds to produce aldol-intermediate compounds, and subjecting the intermediate compounds to a cyclodehydrative mechanism to produce 2,4,6-trinitrotoluene (TNT) compounds in an environmentally friendly manner. Another embodiment includes an environmentally friendly method for making 2,4,6-trinitrotoluene (TNT) compounds comprising, providing nitromethylamino-hexafluorophosphates, providing dinitro-compounds, reacting the trimethinium hexafluorophosphates with the dinitro-compounds to produce aldol-intermediate compounds, and subjecting the intermediate compounds to a cyclodehydrative mechanism to produce environmentally friendly 2,4,6-trinitrotoluene (TNT) compounds. Embodiments of the present invention include the 2,4,6-trinitrotoluene (TNT) compounds produced by the methods of described above.
