Since Sodium carbonate isn't very soluble in IPA, I'm trying to mix and remove some Sodium Carbonate to see if it grabs any undesired compounds. In another batch, I also tried just very salty saltwater, hoping some undesired parts might get trapped in the saltwater, which separates from the alcohol with some patience (see video: [MEDIA=youtube]I5wuMGNsdHk[/MEDIA]).  These are just stabs in the dark, so maybe Transform can lmk if these are futile efforts to get closer to pure DMT.
