A method to convert surplus nitroarene explosives (picric acid, ammonium picrate,) into TATB is described. The process comprises three major steps: conversion of picric acid/ammonium picrate into picramide; conversion of picramide to TATB through vicarious nucleophilic substitution (VNS) of hydrogen chemistry; and purification of TATB.

Nitro-substituted arylhydroxylamines and alkyloxyamines have been oxidized to polynitroaryl compounds by utilizing ozone.Polynitroanilines have been oxidized to polynitroaromatics by peroxydisulfuric acid generated in situ from SO3 and ozone.Thus N-hydroxy-2,4,6-trinitroaniline (1a) or N-methoxy-2,4,6-trinitroaniline (1b) was cleanly oxidized to 1,2,3,5-tetranitrobenzene (2) by reaction with ozone in methylene chloride.Weakly basic amines such as pentanitroaniline (10) can conveniently be oxidized to hexanitrobenzene (11) in high yields by simply dissolving the amine in oleum and introducing ozone.A variety of substituted arylamines have been oxidized to polynitroaromatic compounds by using these two oxidation techniques.
