I did research and a little bit of experimenting with salting out ethanol out of vodka and no I did not drink it because I don't drink. the picture above is high concentration of ethanol on top and water with potassium carbonate on the bottom dissolved into it.
I am here trying to archive my research onto the fediverse and let the community preserve the science I have done. now I have a PDF file of this discourse post I made. https://discourse.eom.dev/t/salting-out-recommended-procedure-by-solidheron/434 and I don't seem to have any place to put it and I'm up for suggestions.
if you do want to read the post id recommend skipping the procedure and reading the second half that goes into why you should. procedure is put first because the HOW is more important than the why. please feel free to comment on any mistake I made in the post or if you have any suggestion to improve on it.
After decanting the alcohol can you precipitate out the salt?
I haven't experiment with dessication, but you can get salt back after salting out and even use it for future salting out. I should run it few more times to get a feel for how effective the resulting potassium carbonate is.
I mean getting it out of the alcohol, or maybe I mean getting it out of the water in the alcohol. I don't think reclaiming the salt from the lower level is hard.
I don't think much potassium carbonate dissolve in alcohol. I lit the ethanol on fire and couldn't tell if any residue of either water or potassium. I never tasted much of the ethanol since I don't want to drink alcohol. Apparently it's insoluble in ethanol.
Potassium carbonate is suitable for consumption up to 100 grams a day
When you ignited it would potassium carbonate in the water in the alcohol have formed KOH? Maybe you could detect pH?
I don't ignite the water part just the ethanol part. I just assume there is some level of water in the ethanol part and it turns into vapor when ignited.
Seems like ph sensor for alcohol would be expensive. I probably should evaporate the alcohol layer to see if I get any potassium carbonate back. Since it's conceivable that the potassium carbonate could vaporize or form into potassium carbonate.
Apparently it's not likely to form KOH. I know electrolysis
Yes that's where I was suspecting you could have taste altering salts.
I was just imagining pH strips.
that's a good idea.
