ok so i do not shoot anything at all, but i have been looking at micron filters to clean up drugs. Would i be wrong to say that if i mixed up water with something like coke and ran it through the filter and then dried it back out again, would i then have pure cocaine? or is it more complicated than that?
 
The micron filter is just like a cotton ball but with really tiny pores. You could filter cocaine from stuff that didn't dissolve in water, but it won't remove water-soluble cuts.
 
If you are interested in cleaning up coke you should look at acetone. Coke happens to have the property where it is insoluble in acetone however most polar molecules will be soluble in it.
 
yea i know about taht, just seems like a bit of a process, and its not just coke i was interested in, but mdma too. as i dont think theres a way to purify M? maybe heroin if i ever decide to try snorthing it once, dont know if thatll happen though.
 
The only substances that would be removed are bits larger than the pore size of the micron filter. Think the smallest you can get are .22 microns or somesuch.

I think you would be wanting solvent extractions to purify your drugs.
 
I'm actually interested in this too. All these A/B extractions take a lot of time and work and supplies I can't have or get to. I wish the whole micron thing worked, I'd be set
 
Well... yes and no. A normal a/b will extract basically every alkaloid and leave the non-alkaloids behind. But levamisole is not so stable at acid pH and can decompose to more easily removed compounds. Or....

The (base forms) of Procaine, benzocaine, levamisole are hexane insoluble.
Cocaine (base from) is hexane soluble.

Go find some heptane, hexane, "petroleum ether", or "ligroin". Make a cocaine solution in distilled water and gently add baking soda or very dilute NaOH in water until cocaine falls out of solution (too much alkali will destroy the coke - you have to look up the pKa of cocaine), then add some hexane, mix well, let it settle, then skim the hexane off and keep it. Do that a few times, combine the hexane layers (containing hopefully mostly cocaine freebase), dry them over anhydrous sodium sulfate, calcium sulfate, magnesium sulfate etc. and then you can either evaporate the hexane to get smokeable freebase, or set up a hydrogen chloride generator and bubble HCl through it, to get much cleaner and purer cocaine HCl.

cheers, forgot about that thread. thanks for explaining it quick n dirty. i dont use enough coke to warrant using that. nor can afford enough to make it worthwhile.
 
What would the method of drying the hexane be?
Simply leave them in the same container and the anhydrous substance will naturally absorb the water from the hexane to form its hydrate?
 
im no expert here, but could you not extract it as you would butane from butane hash oil. You could get a vacuum extractor and properly purge it.

What's the purpose of drying the hexane layers with the cocaine in it? And what's the advantage of using HCl gas instead of aqueous HCl?

Minimize exposure to water. Cocaine is an ester which can be attacked by water in acidic/basic conditions, which destroys the stimulant activity rapidly. Using aqueous HCl, especially for longer than about 15 seconds or with heating, is a good way to destroy large swaths of what you're trying to purify.

Drying the hexane is probably less critical than using "dry" HCl, like a solution in methanol, 'cause hexane has such low water solubility in the first place. But it can't hurt.
