oil from potassium carbonate?
« on: November 13, 2019, 01:29:09 PM »
Hi all
A while ago, I was using lab grade potassium carbonate to dry some 180 proof ethanol. I had maybe about a cup of pot carb sitting in a mason jar filled with spirit and left it sitting for a while. What was strange was that the ethanol appeared to start pulling an oil from the pot carb. The alcohol turned pale yellow. I decided to leave it a bit longer and it turned orange. After distilling off the alcohol, I discarded the oil, but I'm curious now. Anyone know what that could have been?
Thanks

Are you sure it wasn't something from the mason jar?

Hard to know for sure, as it was a while ago. But I think I remember the jar being cleaned with distilled water and then dried with a paper towel.

What was the source of your ethanol.
Was it lab grade also.
