钼氧卟啉(Mo^VO(TPP)Cl)和二甲基亚砜(DMSO)反应动力学和反应机理研究

STUDY OF KINETICS AND MECHANISM FOR THE REACTION BETWEEN MOLYBDENUM (V) TETRAPHENYLPORPHYRINE (Mo^vO (TPP)CI) AND DIMETHYL SULFOXIDE (DMSO)

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。

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