What would be the most practical process to prepare glacial acetic acid from sodium acetate?

I'm thinking to react the sodium acetate with an acid to convert the solution to acetic acid and sodium salt but I'm not sure of the most practical way to proceed from here without distillation (which seems impractical).

I think solvent extraction (using a protonated solvent such as $\ce{CH2Cl2}$) then removal of the solvent would be a way but I'm not sure.

I would like to hear from someone who's done it before.

    $\begingroup$ I do not think there is an insoluble sodium salt and distillation of glacial acetic acid just sound incredibly dangerous and horrifying. $\endgroup$ Commented Sep 3, 2015 at 6:31
  • $\begingroup$ I don't see anything wrong with distillation of acetic acid per se, so it's a way to go as long as it happens under fume hood. Distillation of bromine or nitric acid is way more dangerous and still is used. $\endgroup$

    $\begingroup$ @Joel Same with nitric acid. Still, it is prepared by distillation from reaction mixture of sulfuric acid and potassium nitrate. Same is probably applicable to acetic acid. Or, in case you are not brave enough, the traditional way is a way to go (freezing the azeotrope) $\endgroup$

  • $\begingroup$ I'll take that on board thanks , I'd like to find a way to do bit by solvent extraction. I'd rather distill a suitable solvent than the actual acid it's much quicker. It's not a matter of being brave enough I understand the variables its about practicality. $\endgroup$
