How should the filtrate obtained from the production of ammonium chloride using glycine mother liquor be treated?
Thread Content
The glycine mother liquor is dealcoholized through distillation, and then ammonium chloride is concentrated by evaporation. Ammonium chloride is filtered to yield a filtrate that is red in color and contains mainly urotropin, glycine, ammonium chloride, and methanol. What substance is responsible for the red color inside? Burning it produces a large amount of white smoke; are there any other processing methods available to deal with this?
Alkali (lime) can be added + oxidation treatment
