摘要
对以乙醇胺和丙酮为混合底物、硫酸锰为催化剂、溴酸钾作氧化剂、硫酸为介质的化学振荡反应新体系进行了研究,描述了该体系的振荡特性,研究了各物质初始浓度、反应温度、催化剂等对振荡行为的影响.该振荡反应诱导期、周期与反应温度间的关系符合Arrhenius方程,并测得反应诱导期活化能Ein=51.64 kJ/mol,周期活化能Ep=103.23 kJ/mol.
The chemical oscillating reactions in the system of ethanolamine-Acetone-BrO3-Mn^2＋- H2SO4 was studied. Effects of many factors on the oscillation were examined.The effect of concentration of reactants, reaction temperature, catalyst on the oscillating reaction were also under investigation. The relationship between the inducement period, period energy and temperature were in good agreement with Arrhenius Equation. The obtained inducement period energy and period energy of the oscillations are 51.64 kJ/mol（Ein） and 103.23 kJ/mol（Ep）. The mechanism of the oscillations is also discussed briefly.
