2,4,6-Trinitrobenzoic acid
# 2,4,6-Trinitrobenzoic acid

2,4,6-Trinitrobenzoic acid (TNBA) is an organic compound with the formula $(O_2N)_3C_6H_2CO_2H.$ It is a high explosive nitrated derivative of benzoic acid.

## Preparation and reactions

2,4,6-Trinitrobenzoic acid is prepared by oxidation of 2,4,6-trinitrotoluene (TNT). It is formed by oxidation of TNT and nitric acid with chlorate and with dichromate.

Upon heating, 2,4,6-trinitrobenzoic acid undergoes decarboxylation to give 1,3,5-trinitrobenzene. Reduction with tin gives 2,4,6-triaminobenzenoic acid, a precursor to phloroglucinol (1,3,5-trihydroxybenzene).
