conditions, ferroin (Fe(phen)32+) behaves differently from Ce(III) or Mn(II) ion as a catalyst for the Belousov-Zhabotinsky (BZ) reaction with allylmalonic acid (AMA). The effects of bromate ion, AMA, metal-ion catalyst, and sulfuric acid on the oscillating pattern were investigated. The kinetics of the reaction of AMA with Ce(IV), Mn(III), or Fe(phen)33+ ion was studied under aerobic or anaerobic conditions
在搅拌批次实验和有氧条件下,作为 Belousov-Zhabotinsky (BZ) 与烯丙基丙二酸 (AMA) 反应的催化剂,铁蛋白 (Fe(phen)32+) 的行为不同于 Ce(III) 或 Mn(II) 离子. 研究了溴酸根离子、AMA、金属离子催化剂和硫酸对振荡模式的影响。在有氧或无氧条件下研究了 AMA 与 Ce(IV)、Mn(III) 或 Fe(phen)33+ 离子的反应动力学。有氧条件下金属离子与 AMA 反应的活性顺序为 Fe(phen)33+ > Mn(III) > Ce(IV) 而 Mn(III) > Ce(IV) > Fe(phen)33+在厌氧条件下。在有氧或无氧条件下,RCH(CO2H)2(R = H(MA)、Me(MeMA)、Et(EtMA)、烯丙基(AMA)、n-Bu(BuMA)、Ph(PhMA)的反应性顺序, Br (BrMA)) 是 PhMA > MA
