The oxidation of hydrazine by an aqueous acid perchlorate medium is catalysed very efficiently by TcO4- ions in a manner recalling the nitrate ion system. The reaction shows an induction period followed by a fast stage of evolution of N2, and a high turnover number (>60) but no residue of unreacted hydrazine is left in contrast to the nitrate system, especially under strongly acid conditions. The concentration of Tc(IV) in the system goes through two maxima as reaction proceeds, the first being extremely sharp, the second much broader. This complex kinetic behaviour has been computer-modelled reasonably successfully. The colour changes depend on the acidity of the system, but some coloured products have been characterised by UV/VIS and/or ESR spectroscopy.
