Reaction Steps
According to this invention, the 4-nitro group or trinitrotoluene (TNT) is selectively reduced by H2S in p-dioxane to produce 4-amino-2,6-dinitrotoluene. This latter compound is then nitrated with HNO3 in H2SO4 to produce pentanitroaniline. Finally the pentanitroaniline is reacted with NH3 in benzene, methylene chloride or another suitable solvent to produce a quantitative yield of TATB. The method of this invention is easily carried out and all reactants are inexpensive.
