Distillation at 3 Fahrenheit difference in boiling point?
« on: April 06, 2018, 02:42:48 AM »
I am trying to separate Ethanol from methyl ethyl ketone.

The difference in boiling point is 3 Fahrenheit, Methyl ethyl ketone has the higher.

Can I separate them with a vigeroux column?

Any suggestion on how to get a complete separation without traces/residues of one another in each other?

Thank

Just thought I’d add a patent as well

Try azeotropic separation with an entrainer.  Look it up!
