How to purify residues containing hexachloroethane
Thread Content
Who has a good method to purify hexachloroethane from residues containing hexachloroethane and various organic solvents? There are also several preliminary plans, but various problems will arise when trying to put them into practice. I wonder if there’s any simple and easy way?
This is the chlor-alkali section; it can’t answer your question
Also, I don’t know what your other solvents are, so I can’t answer.
Other solvents mainly include carbon tetrachloride, tetrachloroethylene, pentachloroethane, hexachlorobutadiene, as well as the high-boiling substance hexachlorobenzene.
Taking advantage of different boiling points, evaporation and condensation (sometimes requiring multiple stages or repetitions)； Settling, stratification, and filtration with density differences ； Some can use adsorption or separation methods ； By taking advantage of the difference in freezing points, crystallization methods can be used; membrane separation is another option, as well as chemical methods.
