I couldn't find a good info on the matter, so how could MEK be purified most conveniently when it has been recovered from water solution? It forms
azeotrope with water, and some patents regard the matter, but they generally use industrial-wise methods like high pressure distillation, etc.
I read somewhere that it could be dried with a desiccant and distilled pure? Desired product is anhydrous MEK.

It’s in the wiki

Whichever drying agent is most convenient for you.

Ah, my bad, didn't look thoroughly enough.
It appears that I might want to first fractionate the mek as it's merely stripped off a reaction, and then do the drying.
