Abstract

In a stirred batch experiment, ferroin (Fe(phen)32+) behaves differently from Ce(III) as a catalyst for the Belousov-Zhabotinsky reaction with ethyl- or n-butyl-malonic acid (EtMA or BuMA). The effects of bromate ion, organic substrate, metal-ion catalyst, and sulfuric acid on the oscillating pattern were investigated. The kinetics of the reactions of methylmalonic acid (MeMA), bromomethyl-malonic acid (BrMeMA), EtMA, bromoethylmalonic acid (BrEtMA). BuMA, bromo(n-butyl)malonic acid (BrBuMA) with Ce(IV) or Fe(phen)33+ ion were studied. Under aerobic or anaerobic conditions, the order of reactivity toward Ce(IV) oxidation is MeMA > EtMA > BuMA > BrMeMA ≫ (BrEtMA, BrBuMA). Under aerobic conditions, the order of reactivity toward reacting with Fe(phen)33+ ion is MeMA > (BuMA, EtMA) ≫ (BrMeMA, BrEtMA, BrBuMA). The experimental results are rationalized.
