摘要

采用脉冲辐解技术，利用竞争动力学方法测定了中性条件下3种羟基肉桂酸衍生物（咖啡酸、阿魏酸和芥子酸）与超氧阴离子自由基的反应速率常数，结合稳态分析，探讨了相应的反应机理。

Abstract

Using pulse radiolysis techniques the reaction rate constants of hydroxy-cinnamic acid derivatives (HCAD) with superoxide radical anion (O,2,-•,) were obtained by competition reaction kinetic analysis. The reacting mechanism was proposed based on the HPLC analysis of final products and UV spectrophotometry.
