degassing cold solvent? pH?!?

soooo…some clown came visiting while I was out of town, and moved most of my solvent from the 55gal drum it was in into 5gal cans with holes punched in the lids.

then they buried those cans in dry ice.

now all my solvent is effervescent…which means it won’t pump worth a damn (gear pump).

it probably also means that my ethanol is now acidic.

as a first approximation I was going to throw 15 gal in a keg and try degassing under light vac.

will this do anything to reduce the carbonic acid?
or will I need to adjust the pH after degassing?!?

re-distil it all

3

would this actually do anything? assuming that no water got into the ethanol, I would guess that re-distilling would remove some of the dissolved CO2, but would carbonic acid remain in the boiling flask at the very end of distillation?

4

Would carbon filtering the ethanol and then pumping thru a mol sieve remove some of the water content, prior to re-distilling?

5

Added 10gal into my Cryobath (ie retired it from solvent duty)

Will probably do the same with the last 5gal.

Hoping that redistilling solves the problem.
pH strips on the list…
