研究了Ce 4+氧化溴代丙二酸（BZ）反应中产生一个Br离子所需的Ce 4+离子数.我们发现比率为1：1，与Jwo和Noyes（J. Am. 1975，97，5422）。当氧气从系统中排除时，我们发现比例为2：1。与Belousov-Zhabotinskii反应理论模型的假设相反，体系中丙二酸的存在对溴化物的产生没有影响
We investigated the number of Ce 4+ ions required to produce one Br ion in the oxidation of bromomalonic acid by Ce 4+ under conditions appropriate to the oscillating Belousov-Zhabotinskii (BZ) reaction. We found a ratio of 1:1, in agreement with earlier results by Jwo and Noyes (J. Am. Chem. Soc. 1975, 97, 5422), in the presence of oxygen. With oxygen excluded from the system, we found a ratio of 2: 1. The presence of malonic acid in the system had no effect on the bromide production, contrary to the assumption of recent theoretical models of the Belousov-Zhabotinskii reaction
