Abstract

KBrO(3) and H(2)SO(4) produce an oscillating system in batch when the proper combination of substrate concentrations, stirring rates, and temperatures is used. Bromide present as an impurity in KBrO(3) also takes part in the reaction. In many Belousov-Zhabotinsky (BZ) systems the above substrates are used and mixed with only an organic substance or with an organic substance and a catalyst, and the simple bromate oscillator cooperates with an organic substance, a catalyst, or both. The bromate oscillator found in this work is the simplest one in the BZ system composed of BrO(3)(-), H(2)SO(4), an organic substance, and a catalyst.

摘要

当使用底物浓度、搅拌速率和温度的适当组合时，溴酸钾（KBrO₃）和硫酸（H₂SO₄）在分批操作中会产生一个振荡系统。作为杂质存在于溴酸钾中的溴化物也参与反应。在许多贝洛索夫-扎博京斯基（BZ）系统中，使用上述底物并仅与一种有机物质或与一种有机物质和一种催化剂混合，简单的溴酸盐振荡器与一种有机物质、一种催化剂或两者协同作用。在这项工作中发现的溴酸盐振荡器是由溴酸根离子（BrO₃⁻）、硫酸、一种有机物质和一种催化剂组成的BZ系统中最简单的一种。
