Belousov-Zhabotinskii Reaction in Tyrine-KBrO3-H2SO4-Propanone System Catalyzed by MnSO4 Respectively Tao Tingxian, Wu Zhichuan, Gao Hongjun (Biochemical Engineering Department, Anhui University of science and technology 241000) Abstract This paper presents a study on the concentration range of reactant in oscillation reaction of Tyrine-KBrO3-MnSO4-H2SO4-Propanone system, which gives a typical oscillating wave. Effects of many factors on the oscillation reaction have been examined. The oscillation period and amplitude as function of the initial concentration of each reactant have been studied. The relationship equation between period and concentration and the apparent activation energy during induction and oscillation period have been obtained. Based on the resalts, the oscillation reaction model and reaction mechanism Key words Belousov-Zhabotinskii Reaction, Chemical oscillation, Tyrine-KBrO3-MnSO4-H2SO4-Propanone system, Reaction mechanism, Tyrine 酪氨酸-溴酸钾-硫酸-丙酮在硫酸锰催化下的 B-Z 振荡反应 陶庭先 吴之传 高红军 (安徽工程科技学院生物化学工程系 芜湖 241000) 摘要 本文研究了酪氨酸—溴酸钾—硫酸—丙酮在硫酸锰催化下的化学振荡反应，对振荡的影响因素进行了研究和讨论。运用正交实验法确立了振荡反应进行的浓度范围。获得振荡的诱导期和周期与反应物浓度之间的变化趋势曲线，以及振荡反应在诱导期和振荡期的表观活化能 。根据反应过程中的现象和实验数据，建立了振荡反应的模型和反应机理，进而为反应过程和机理研究提供一些理论依据。 关键词 化学振荡 诱导期 振荡周期 酪氨酸 陶庭先 40 岁，男，硕士，副教授，从事应用化学研究。 E-mail:tw3@auts.edu.cn 安徽省教育厅自然科学基金资助项目(2001kj052) (PDF全文下载c04003)
