Recrystallisation with acetone

Migrated topic.

Viracocha

..still lc..
The freebase is freely soluble in acetone, however it seems that the acetone will not dissolve an non polar oils. I could be wrong as this is only going on preliminary observation, but nonetheless I am curious

Has anyone tried this?

It may be quite beneficial over rex with shellite / naptha as when either of these solvent are heated, the will pickup some of the oil again.

Due to the freeze precipitate properties of shellite / naptha, they may still be the preferred solvent for rex, but perhaps for crystal growing acetone may be perfect due to it's high evaporation rate without needing any help

Also,
Could someone shed some light on how the properties of solvents (i'm guessing the dielectric constant value has the most impact) varies the solubility of a given solute?
 
Freebase is indeed very soluble in acetone . SWIM has tried your suggestion but has not been amazed - neither has reached any greater levels of purity with it. SWIM also thinks that acetone can dissolve non-polar oils as good as spice.
 
hmm bummer..

what about for crystal growing?
maybe evaporation is too fast... perhaps shellite is perfect
bah, if it ain't broken don't fix it i always say..
well, it was worth a thought at least

Any comment on the dielectric constant?
 
SWIM has crystallized DMT in acetone before. It works, but not as well as heptane. Sometimes crystals don't form in acetone, especially if a fan is used because it evaporates too fast for crystals to form. When crystallizing with acetone don’t use a fan or any heat.

You can probably crystallize DMT citrate better in acetone than freebase DMT.

Acetone dissolves a lot of non-polar stuff: oils and fats, freebase alkaloids, etc. But it also dissolves some polar stuff too. But it is very selective in what it dissolves at both ends.

Acetone can dissolve freebase bufotenine which is slightly non-polar. It can also dissolve citric acid which is very polar. If you dissolve freebase bufotenine in acetone and add citric acid, it precipitates bufotenine citrate which is also very polar. Acetone is unusual in this way. This same trick also works for some other alkaloids, but it doesn’t work for DMT. Freebase DMT and DMT citrate are both soluble in acetone.
