摘要: |
对超声辅助条件下14种酚类化合物的衍生化效率进行了研究。选取衍生反应的温度和时间等对衍生化效率有决定性影响的参数进行优化,结果发现,在75℃下反应60 min,14种酚类化合物的衍生化效率最优,是非超声辅助条件下衍生化效率的0.97~44.4倍,提升明显。该方法性能稳定、抗干扰能力强,能够满足水中酚类化合物衍生反应的需求。 |

Abstract: |
The derivatization efficiency of 14 phenolic compounds under ultrasonic assisted conditions was investigated. The parameters that have a decisive influence on the derivatization efficiency, such as the temperature and time of the derivatization reaction,were selected to be optimized. It is found that the derivatization efficiency of 14 phenolic compounds is the best at 75 ℃ for 60 min, which is 0.97~44.4 times that of the derivatization efficiency under non ultrasonic assisted conditions. The improvement is obvious. This method has stable performance and strong anti interference ability,and can meet the requirements for the derivation of phenolic compounds in water. |
