摘要： 本文应用停-流快速反应动力学测定仪器研究氯钼氧卟啉(MoVO(TPP)Cl)同二甲亚砜(DMSO)的反应动力学. 实验结果表明, 反应至少含有四个基元步骤. 动力学研究得到驰豫时间τ与加入的初始二甲亚砜(DMSO)的浓度成线性关系, 本文提出了一种反应机理, 比较满意地解释了上述化学反应动力学实验结果。

Abstract: The kinetics of the reaction of MovO(TPP)Cl and DMSO has been studied with a stopped-flow spectrophotometer. The results show that the reaction is a complicate one which includes at least four elementary steps. The relaxation time (τ) varies linearly with the initial concentrations of DMSO. A reaction mechanism was suggested which can explain the experimental results satisfactorily.
