Abstract
In the usual synthesis of s-triaminotrinitrobenzene (TATB), s-trichlorobenzene (TCB), is first nitrated to s-trichlorotrinitrobenzene (TCTNB) and then aminated with ammonia. The s-TCB is obtained as a byproduct from another synthesis operation or from 2,4,6-trichloroaniline. Isomerization of 1,2,4-trichlorobenzene is another possible source. Eastman Chemical Company (Kingsport, Tennessee) is a large producer of 2,4,6-trichloroaniline (TCA) which is used in the synthesis of photographic chemicals; however, they are unwilling to convert this to either the s-TCB or trichloronitrobenzene due to environmental concerns. They have proposed instead to convert TCA to 1,3,5-trichloro-2-nitrosobenzene in large quantity.
