You could do that. The metallic Potassium would react quicker (and safely) though you are right to avoid the metallic sodium. The other advantage of the metallic potassium is that it will react with the water as well as the alcohol. The end result is a mixture of KOH and CH3CH2OK. The

Why not set up a waste heat exchanger. That would allow you to recapture some of the heat needed for distillation to heat the next batch. mtushmoo wrote: Remember, Boiling requires heat to make it happen, even if it is occuring in a vacumn. The vacumn making the ethanol boil will absorb

You could use a Carbon dioxide scrubber to remove the CO2 and then still be able to use a vacuum for distillation. The House of Jade wrote: Well, you are now talking about vacuum fermentation for which there is a patented process. Stripping off ethanol as it is produced solves one problem
