| 摘 要： | 在间歇式反应器中成功地实现了己二腈(ADN)在近临界水中的水解。考察了m(ADN)/m(水)比、温度、时间、m(ADN)/m(添加物)比、添加物种类以及压力对每种产物产率的影响。通过高效液相色谱检测，己二腈在近临界水中水解主要生成五种产物，分别为5-氰基戊酰胺、己二酰胺、5-酰胺己戊酸、己二酸和微量的5-氰基戊酸。实验结果表明，ADN浓度和时间的改变对己二酰胺、5-酰胺基戊酸和己二酸的产率有明显的影响；时间是影响5-氰基戊酸产率的重要因素；5-氰基戊酰胺产率主要取决于ADN的浓度。

| Abstract: | Hydrolysis of adiponitrile (ADN) in near‐critical water was successfully conducted in a batch reactor. Influences of m(AND)/m(water) ratio, temperature, time, m(AND)/m(additive) ratio, kind of additive and pressure on the yield of each product were investigated. Five compounds resulting from the hydrolysis of ADN, including 5‐cyanovaleramide, adipamide, adipamic acid, adipic acid and trace of 5‐cyanovaleric acid, were detected by high performance liquid chromatography. The results showed that change of ADN concentration and temperature had significant influences on the yields of adipamide, adipamic acid and adipic acid; time was the significant factor for the yield of 5‐cyanovaleric acid; and the yield of 5‐cyanovaleramide was more dependent on the ADN concentration. |
