甲苯法生产己内酰胺废液中的己内酰胺、环己羧酸、环己羧酸磺酸和有机油的分离提取方法
摘要：
本发明提供了一种甲苯法生产已内酰胺废液中已内酰胺、环已羧酸、环已羧酸磺酸和有机油的分离提取方法。本发明不仅解决了废液对环境的污染问题，而且有效回收了废液中的已内酰胺、环已羧酸和环已羧酸磺酸等化工原料，且所得有机油燃烧值高，直接作为燃料利用，适用于大量工业废水的连续处理。
摘要（英）：

The invention provides a separation and extraction method for caprolactam, cyclohexane carboxylic acid, cyclohexane carboxylic sulfonic acid and organic oil in waste liquid generated in caprolactam production by the toluene method, which not only resolves the problem of environment pollution by waste liquid but also effectively recovers industrial chemicals such as caprolactam, cyclohexane carboxylic acid, cyclohexane carboxylic sulfonic acid and the like in the waste liquid. Furthermore, obtained organic oil which is high in combustion value can be directly used as fuel, and the method is applicable to continuous treatment of a great quantity of industrial waste water.
