Hey guys,
I used to have some problems with M.HCl re-x in the past, so I rather sticked to the ipa/acetone/mek washes + activated charcoal purification in my extractions.
But recently I finished with not as white M.HCl as would be required and rather than another wash or charcoal round decided to try re-x again. So I decided to use hot methanol in minimal amount to dissolve mescaline and added quite a lot of hot dry ipa/mek. Boiled for some time to evap the methanol and put into the freezer for 12h. Mescaline crystallized on the botton and was filtered out. Remaining ipa/mek was stored on the shelf at room temp for 24h.
To my surprise there was quite significant crystallization in the erlenmeyer flask with the ipa/mek, regardless of the higher room temp, the difference between the room temp and the freezer was >40C.
These crystals were much more pure than crystals obained by crystallization in the freezer.
So my question is - does anyone have an explanation? I believed everything should crystallize when the solution is cold. Why is it crystallizing even when most of the mescaline is already out of the solution and the temperature rises by 40C?
I know that while re-x'ing dmt from heptane, when I remove it from the freezer after 12h, filter out and put the heptane into the freezer again, there is some residual crystallization, but this is because of the low temps of the freezer. If the heptane is left in room temp, there is no any crystallization, as expected.
