研究了锰催化丙酮酸在水溶液中臭氧化的反应机理和动力学。在2.0 ~ 4.0的pH范围内进行的实验表明，悬浮mno2颗粒和溶解Mn离子分别激活了非均相和均相催化机制，从而增强了反应活性。阐明了均相机理和相关动力学。
Reaction mechanisms and kinetics of manganese-catalyzed ozonation of pyruvic acid in aqueous solution are investigated. Experiments performed in the pH range 2.0–4.0 show that the reactivity is strongly enhanced by heterogeneous and homogeneous catalytic mechanisms, which are activated by suspended MnO2particles and by dissolved Mn ions, respectively. Homogeneous mechanisms and related kinetics are elucidated.
