三氯吡啶醇钠加成废液的处理和循环使用

Processing and Recycling the Trichloropyridin-2-Ol Sodium's Additive Waste Liquid

[目的]介绍一种三氯吡啶醇钠加成废液的处理方法。[方法]向三氯吡啶醇钠的废液中通入氯气。[结果]废液中的丙烯腈转化成2,2,3-三氯丙腈和三氯乙酰氯,实现了三氯吡啶醇钠的回收。[结论]该处理方法简单,适用于工业化三氯吡啶醇钠加成废液的处理。

[Aims] The paper presented a new synthetic method to process trichloropyridin-2-ol sodium＇s waste liquid. [Methods] Chlorine gas was introduced into trichloropyridin-2-ol sodium＇s waste liquid. [Results] The acrylonitrile was translated to 2,2,3-trischloropropionitrile and trichloroacetyl chloride, and the trichloroacetyl chloride was recycled. [Conclusions] The processing method is simple, and suitable for trichloropyridin-2-ol sodium＇s waste liquid treatment in industry.
