Due to a detailed analysis of NMR spectra of the reaction solutions with different composition obtained by the aqueous‐phase catalytic (Pd/C) hydrogenation of 2,4,6‐trinitrobenzoic acid, the intermediate compounds were identified and a more substantiated mechanism was proposed for the formation of the main reaction products—1,3,5‐triaminobenzene and cyclohexane‐1,3,5‐trione trioxime. The condensation of the 1,3,5‐triaminobenzene molecules produced by a complete hydrogenation of 2,4,6‐trinitrobenzoic acid was shown to result in the formation of a paramagnetic heterocyclic compound.
