SWIM's extracting from P. Torch. He had over 600 mg crude, light brown mescaline HCl which was washed with about 20 mL 99% IPA. After the solids were re-collected, however, only 0.165 g remained. Is this an unusually high loss for an IPA wash? 


My friend says he only used IPA because he wants to stick to food-grade reagents. He put about 200 mL of 91% IPA in a glass, and added way more than enough home-made "anhydrous" magnesium sulfate.* He thinks it was an excess amount because the AMS formed 2 layers in the bottom of the glass: 1 solid, clumpy layer, and 1 "dusty" layer. He then stirred the IPA-AMS solution, waited for it to settle, and then drew off only the top 20-30 mL of dried IPA.Virola78 said:My red cat still has to try the washing of mesc using (acetone and) IPA. So he is eager to learn from your experience.
I read about some monkeys that do not have (that) much loss from IPA wash.
Was it the first time you opened the bottle of IPA?
did you use an open glass when you put it in the fridge to precipitate the solids from the IPA?
how did you remove the IPA from the solids? decant? pipette? syringe? dropper?
). This solution was then filtered through a coffee filter. After scraping off the remaining solids from the coffee filter, the filter itself was soaked in distilled water twice to remove any remaining water-soluble mescaline HCl.Phlux- said:ipa often contains water and its not always easy to get 100% dry - mescaline is soluble in that % of water that remains - was ur ipa 100% ipa ?
Phlux- said:rather use acetone - its much easier to dry fully.
soulfood said:If the mescaline was a very dark colour before the wash then this sort of loss is expected.
soulfood said:If too much Hcl was used when salting out, it will pull a lot of crap other than mescaline which is usually the reason for such a loss in mass.
soulfood said:The only other thing I can think of is there was more water than expected in your IPA. Always keep your solvent washes to evap if something unexpected happens.

The cat has done 3 batches of 25ml 2% HCl. There were some nice crystals in the evap plates. Some looked like the fine clear crystalshards that Phlux- has produced and photographed. But there was also an orange coloured stuff present. All the stuff was easily scraped (broken) off the evap dish. (The acetates some time ago were allot more difficult to scrape off the dish.)
Anyways, the dirty mesc-HCl was washed twice with 2x 10ml acetone, using a small shotglass and a dropper. In between these washes the stuff was not left to dry. Some tan colour is washed off by the acetone, but the mainproduct is still very much tan coloured. Drying at the moment, then an IPA wash will be done.
Why is this washed product not fairly white yet? was the acetone wash not rigorous enough?
Or will the IPA wash off the remaining dirt?
Or is the pulled product just too dirty to clean up using acetone and IPA?
Silly red cat.

w0mbat said:Did you powderize the crude mescaline HCl in the acetone, or just pour the acetone on top & then pour it off? Powderizing it should make it dissolve more impurities (and more mescaline HCl...)

narmz said:Do you have food grade HCL?
narmz said:I don't know, if you're trying to stick to more safe stuff you might wanna look into carbonates, they can be cleaned with ipa from what i've heard.
