Our company does not have distillation towers. The mother liquor contains chloroform and pyridine; in the past it was possible to separate chloroform from pyridine, but this time the chloroform contains about 1% pyridine, and re-distillation cannot remove this compound. Water washing also has little effect – what should we do?

Chloroform has a boiling point of 64 degrees. What is pyridine? A 1% concentration doesn’t seem to have much impact, so it shouldn’t be a problem

Neutralization with hydrochloric acid is carried out to form a salt of pyridine; subsequent washing and separation by layering ensures the removal of pyridine from chloroform

I would like to ask what materials should be used for the tower and pipelines in the distillation of chloroform and pyridine? How is the corrosion?
