| Abstract: | In this paper, we found that in aqueous solutions, Ni (Me_6 14]-4, 11 -dieneN_4)]~(2+) and Ni (Me_2Et_4 14]-4, 11-dieneN_4)]~(2+), can act as catalysts in the bromate-gallic acid (or pyrogallic acid) -sulfuric acid system. The regions of existence of concentration oscillations for the systens catalyzed by Ni(Me_6 14]-4, 11-dieneN_4)]~(2+) and (Ni (Me_2Et_4 14]~(-4), 11-dieneN _4)]~(2+) have been determined. The concentration oscillations of these systems are damped due to the slow consumption of the catalyst Pyrogallic acid can alsobe servec as organic substrate to produce oscillations.In some espects, the catalyzed oscillations behave similarly to theNiATH] ~(2+) catalyxed ones. |
