General description
The electrochemistry of 1,2-dinitrobenzene in the presence of 1,3-diphenylurea was studied. The kinetics of the aromatic nucleophilic substitution reactions of 1,2-dinitrobenzene with butylamine and piperidine were investigated as a function of the amine concentration and temperature.
Application
1,2-Dinitrobenzene was used as internal standard for analysis of the explosives, TNT, RDX, and tetryl in sea water by vapor phase chromatography with the nickel-63 electron capture detector.

[reaction: see text] The electrochemistry of 1,2-dinitrobenzene (1,2-DNB), 1,3-dinitrobenzene (1,3-DNB), and 1,4-dinitrobenzene (1,4-DNB) is strongly affected by the presence of 1,3-diphenylurea. In DMF, the second reduction potential of all three DNBs shifts substantially positive in the presence of the urea
