Method for separating 2,4-dichlorophenol and 2,6-dichlorophenol mixtures
Thread Content
Their boiling points are quite close, making distillation an ineffective method for separation. How can they be separated?
The boiling point difference between the two is 8 degrees, and precise distillation should be sufficient to separate them; the melting point difference is also only a little over 20 degrees, making crystallization rather difficult.
Distillation: Seek a professional distillation design company; vacuum distillation can be used to separate 2,4-D using this method
It can be separated by liquid-liquid extraction; I have worked on this area
