由4,4′-二氰基二苯醚水解制取4,4′-二苯醚二甲酸的实验研究

THE DISCUSSION ON 4,4′-OXYBIS BENZONITRILE HYDROLYSED TO 4,4′-OXYBIS BENZOIC ACID

本文论述了从4.4′-二氰基二苯醚制取4.4′-二苯醚二甲酸的实验方法.通过采用碱催化,加压水解以及控制合适的反应温度和反应时间,可以得到高纯度,高产率的产物。

This paper studied experimental method of 4, 4'-Oxybis benzonitrile hydrolysed to 4, 4'- Oxybis benzoic acid, The hydrolysis was conducted in the presence of NaOH and autogenie pres- sure at suitable temperarure and reflux time. The product with high yield and high purity can be obtained with this way.
