  • New method for preparing pentanitroaniline and triaminotrinitrobenzenes from trinitrotoluene
    Patent number: 4248798
    Abstract: Trinitrotoluene is selectively reduced by reaction with H.sub.2 S in p-dine to produce 4-amino-2,6-dinitrotoluene. This latter compound is then nitrated with HNO.sub.3 in H.sub.2 SO.sub.4 to produce pentanitroaniline which is, in turn, reacted with NH.sub.3 in benzene, methylene chloride or another suitable solvent to produce triaminotrinitrobenzene (TATB). TATB is useful as an explosive.
