应用Stopped-flow光谱仪对苯酚在288～313K温度和pH=3.2～9.3的液相臭氧化反应动力学特性进行了实验研究。通过实验及分析认为:苯酚的O_3氧化降解反应中,O_3与苯酚的计量比为3;在不同酸度的实验条件下,苯酚的液相O_3氧化降解的途径及动力学不同。
The kinetic characteristics of phenol ozonation at 288 ~ 313K and pH = 3.2 ~ 9.3 were investigated by using a Stopped-flow spectrometer. Through experiment and analysis, it is concluded that the O_3 oxidation reaction of phenol is 3, the molar ratio of O_3 to phenol is 3. Under different acidity conditions, the oxidative degradation pathway and kinetics of phenol in liquid phase O_3 are different.
