Redissolve in acidic water (I use acidic saltings directly)
Basify
Filter out solids
Wash solids with water
Dissolve in IPA
Evaporate
Wash residue with water
Glad to hear this worked. Two water washes. No yield loss? I personally don't like washing DMT with water, but that's just me.
The first part of the extraction can def be done without an acid, just base the plant material and pull, but then if one would want to clean up, then an acid would be necessary to redissolve, filter, re-evap and basify. Many things could be tried, like vitamin c, citric acid (or maybe even just lemon).
Good to know STB can be used. The acid part of the clean-up extraction employs the insolubility of various matter in an acidic solution. The clean-up works by filtering out this matter, correct? If so then in theory we could dissolve the dirty yield in carbonated water, filter and discard the solids, evap solution to obtain clean freebase DMT. No basing and pulling required.
procedure:
- mix MHRB with excess sodium carbonate, add water to make a paste, spread it in a wide dish and let it dry
- 1-3x pulls with ethanol, filter the pulls, evaporate the ethanol
- redissolve dirty yield in carbonated water, filter and discard the solids
- evaporate the carbonated water solution to obtain clean freebase DMT
The only thing to make sure of is that no base from the first STB extraction dissolves in the pulling solvent. Using 96% ethanol and sodium carbonate, some base will dissolve in the solvent and stay in the yield. Then re-dissolve in the carbonated water and stay in the cleaned yield also. Downwardsfromzero mentions that hardly any calcium hydroxide dissolves in 96% ethanol, so food grade calcium hydroxide would be better. With Sodium Carbonate either 99.9% IPA or dehydrated ethanol should be used. Endlessness what's your take on using Anhydrous MgSO4, Sodium Sulphate or Calcium sulphate to dehydrate ethanol? Or will freezing the ethanol solution low enough precipitate out all Sodium Carbonate?
If this works we'd only need:
- baking soda (converted to sodium carbonate by heat in the oven)
- 96% alcohol
- sparkling water
