The kinetics of nitration of 5-bromo-, 5-chloro-, and 5-nitro-2-picrylaminopyridines in 80-96percent sulfuric acid were studied by a spectrophotometric method.The kinetic parameters of nitration were calculated.The UV spectra of the neutral and protonated forms in aqueous sulfuric acid solutions were identified.It was established that the indicated compounds are nitrated in the protonated form.The relative (as compared with benzene) rates of nitration were calculated.
