Cleaning/Purifying Cocaine?

[fairnymph]

Thanks guys!
I think I'll try the ammonia method as I'm a sucker for purity...Cokeboy, thank you for test driving for me.

If you have any procedural questions, or something you've read isn't luminously clear, ask before proceeding. Good luck.

FairNymph - When you've tried it, let me know your impressions.

1. take coke. base it
2. hcl bubble just like makin meth hcl from the oil, except you have a solid, so find an appropriate solvent.
problem solved. large scale? yes. scaleable? yes.

Top oversimplified. Many cuts can base and then to bubble hcl.through will just turn base cits back again. Acetone wash, ethanol recrystalisation then go to a slow titration with 1g with 60ml of distilled water and ammonia of 5-9% 5 is good as it slows the process down as come cuts base out first. Then personally I'd add a little hexane shake it up and pull out all the pure freebase cocaine. Then you can think about re salting it. Probably need to use chloroform and maybe ether too tbh as I don't think the above method is great at getting other cains out. Also iirc acetone is a good solvent for base Coke to bubble hcl. Always open to hearing objections or additional ideas I'm all about harm reduction.

What do you think thinctwo?

(Taken from one of the above threads)
1) Dissolve the cocaine HCL in some water, add some decolorizing carbon and filter.
2) Add 28% aqua ammonia to the solution obtained in step 1 to produce the cocaine freebase and extract the freebase with low boiling petroleum ether.
3) Allow the petroleum ether to evaporate, dissolve the freebase in acteone and, if cloudy, filter again.
4)Prepare a solution of 1:2 conc. HCL in methanol. Use the aqueous HCL/methanol to acidify some acetone and then add to this solution the cocaine freebase/acetone solution.
5) Stir and allow the cocaine HCL to crystallize. Filter and acetone wash.
TO SUMMARIZE:
If any of the concepts are foreign to you (i.e. performing a chemical wash, an extraction or a filter), consider not attempting this.
Also, remember that petroleum ether has wonderful potential as a scarring tool, thanks to explosivity.
Finally, remember the bible: http://www.amazon.com/exec/obidos/A...95868/sr=8-2/ref=sr_8_3_2/002-7711694-8325665

do you know of any cuts that base or not that will dissolve into petroleum ether?

Acetone then ammonia. The peoblem then is youll wind up smoking it before you msnage to convert back to hcl

I might be trying some of these to see if I can produce freebase that doesn’t burn. We’ll see what solvents I can acquire.

The strong coke always seems to burn terribly, very annoying. 20+ yrs later I find smoking freebase my fave - it’s the only thing I like to smoke/vape.

Im also going to try this method. Ive been working on it this week and based about 3g. I used 2 products from diff people and used both ammonia method and bicarb method on half of each. Now I plan on converting it back to HCL (minus sampling some for quality control of course.)
Where does the petroleum ether come in exactly? I just used the ammonia solution I took from around 30% to 6%. Since petroleum ether isn't actually ether can it be substituted for ethyl ether (which is what I have ATM.)
Lastly does anyone know what solvent is best for just recrystallizing cocaine?

I have been wondering about these extracting using another liquid like petroleum ether, if someone could clarify that please. I've been using medium or high flow filters to remove the freebase from the ammonium hydroxide. I am about to do another basification on something else and wanted to double check this technique. Is it something like this:
Adding ether or petroleum ether to the freebase/ammomium hydroxide solution results in an upper and lower solution in which the freebase is in the ether which is extracted and then easily evaporates. The benefit being that easily means quicker here. Or does adding the petroleum ether cause a more dramatic change....maybe something like causing an exothermic reaction in which a bunch of steam is produced until only a chunk of pure freebase remains (just a JOKE.)

Now it's all gone, I won't be buying more. That was a little TOO much fun. I've never been all that much into coke, but... wow.
Less product going in, likely easier on the nasal passages, too.

On a separate, lighter note: I was confused by your name being Cokeboy but your not really even into coke. Is one coke referring to Coca-cola the drink? I think my time with coke has expired as well, it doesnt really do much for me anymore but make me very hot. I abused it beyond repair, which is why I finally decided to start experimenting with this quarter I've had over a year. I was just curious by the way, I don't mean to offend.

My bad For double commenting. I refreshed a couple times and the previous messages didn't load so I figured I never entered it or was dreaming or something. My memory is pretty wonky nowadays.
