How can chlorobenzene and toluene, as well as dichloroethane, be separated in the aqueous phase?
First, one needs to look at the composition and recycling goals. Generally, heterogeneous azeotropic distillation is used to separate water of higher purity from mixed organic compounds; however, the resulting mixed organic compounds are passed through multiple sequences of distillation columns to yield individual pure organic compounds.
These two immiscible substances should settle and separate naturally. If it is in small quantities or in emulsion form, a coalescer can be considered to reduce the time required
See if it’s possible to use water or other solvents for extraction, followed by distillation, or evaporation, and then further distillation.
