I don't have bisulfite, how would that work to remove the MEK? If you think it'd bee really beneficial, it'll appear.
No it really looks like they've designed the mixture to be difficult to separate using distillation.
and washing with water should take care of the butenol.
Like it a lot. That should hopefully remove a lot of MEK aswell.
The MEK's solubility in water decreases as the temperature is raised so I'm just thinking I can bring the toluene mix down to 5 degrees, then do a warm water wash to leech the last of the MEK out of the cold toluene, and in to the fresh warm water.
r.t water washes till satisfied, warm water wash of cold mixture, then a brine wash.
How does that sound?
