- 中文摘要: In a batch-stirred experiment, the Mn(II)-catalyzed reaction of bromate ion with methyl-, ethyl- or n-butyl- malonic acid (MeMA, EtMA or BuMA) exhibits oscillating behavior similar to the prototype Ce(III)-catalyzed Belousov-Zhabotinsky (BZ) reaction with malonic acid (MA). The effects of manganese ion, bromate ion, organic substrate, sulfuric acid, and chloride ion on the oscillating pattern were investigated. Both conventional and stopped-flow spectrophotometric methods were applied to study the kinetics of reactions of Mn(III) ion with MA, MeMA, EtMA, BuMA, bromomalonic acid (BrMA), and dibromomalonic acid (Br/sub 2/MA). The order of reactivity toward Mn(III) oxidation is MA>BrMA>MeMA>Br/sub 2/MA>(EtMA, BuMA). The experimental results are rationalized.
