Hi everybody,

SWIM is wondering if is possible to extract smokable coca from coca leaves in one step.

The well-know method requires: extracting the freebase alkaloid in kerosene, recover it with an acid aqueous solution (agua rica) and then basify this solution to precipitate the water-insoluble coca paste.

The method SWIM is going to study is more simple: putting leaves in acid aqueous solution to extract the cocaine salts , basify this solution and recover the water-insoluble precipitate with a filter.

If SWIM is right, he should get a more crude form of smokable coca (along impurities as well).

SWIM has two questions:

1- Is this method going to work?

2- Coca extraction methods talk about coca paste as a crude smokable form of coca made of coca sulfate. Is coca sulfate melting point suitable for smoking or the methods simply forget to mention the basifying step of coca sulfate?

Any help would be appreciated by SWIM.
 
Just a heads up... nobody uses SWIM here as it makes you sound like a moron. You're fooling nobody.
 
SWIM should read the forum rules instead of copying-and-pasting from websites describing how Pepe in the jungle extracts the alcaloïd from Erythroxylum.
 
Thank you for your kind reply. Aside of "SWIM" , anyone can help with this extraction?
 
I forget the local name of the stuff, in colombia and venezuela there is a crude coca base smoked usually by poor people, it is pretty impure and contains a host of other alkaloids along with the cocaine.
 
I'll try to be more clear.

I'm wondering if possible to precipitate freebase alkaloids and recover them by filtering the aqueous solution.

So I'm talking about a regular A/B extraction skipping the steps of extracting them with non-polar solvent and recover by evaporation.

On a small-scale extraction should be better avoiding too much steps, to loose almost no alkaloids.

I have a link to a full laymans cocaine extraction with pictures if you're interested. I'm not sure if I can post it here, so give me your email and I'll send you it.
 
Should be able to extract the leaves with a weak acid, then basify it, and seperate the precipiate, and that should be smokable. You might be able to heat it and have all the alkaloids melt together and float to the top (i hear this works for making freebase cocaine from powder cocaine), but that might be too easy.

I think that a kerosene wash before basifying can help removing non-polar impurities from the aqueous solution and obtaining a more pure product.

Do you think the freebase cocaine will precipitate and can be filtered or kerosene is needed for extracting it? I always think that after adding ammonia to the acid coca tea, the solution will become milky and no precipitate will form..

The method of melting alkaloid and let them float to the top of the aqueous solution should work. Do you know how it works? Maybe the melted alkaloids are just less dense than water, then float?


P.S.: we are talking about extraction, not synthesis.

It's pretty easy, done it in Colombia. Need a fuckload of leaf though, 1kg to 1g of smokeable product.

Coca leaf, cement, phosphates, petroleum, baking soda. Google that shit, you could do it in your backyard if you ahd the leaf to begin with,

Actually I'm talking about extracting a crude base with water as the only solvent.
 
I agree a waste of time unless you have alot. I have a few thousand grams of coca flour and I still won't waste my time with any extraction. Plus, in [Negronesia] cocaine is cheap; the reagents would cost almost as much as the yield.

The recipes I found on the web for "coca paste" don't always require the use of kerosene.

Actually I found 2 recipes that precipitate the paste directly from the aqueous phase:

Recipe 1: put leaves in water/baking_soda (freebase alkaloids), add dilute sulfuric acid (alkaloids become sulfate salts), filter from impurities, then basify (alkaloids precipitate)

Recipe 2: put leaves in dilute sulfuric acid (alkaloids become sulfate salts), filter from impurities, then basify (alkaloids precipitate)

Which is the difference between the two methods? Which one is going to work?

Leaves are quite expensive so I want to make the best method, please help me.

Thank you

I'd go with #2, but why not just ride down through the hood and pick up a couple of 20 rocks? A lot quicker

Because I can't find a good dealer here.

If I had 5Kgs of leaves I would go for the classic method (leaves+bakingsoda->kerosene->dilute acid etc.) because with this quantity losses are negligible and I will get a more pure product.

But for 1 Kgs of leaves I think it's very difficult to carry that 3 grams of alkaloids through different solvents and then precipitate. I don't want to extract 3 grams of coke dissolved in 5Lt of kerosene with 100ml of water, I will end loosing everything.

So I want to keep the alkaloids in the water phase to prevent any loss:
- extract the leaves with an acidic water solution (I think 2x the volume of the leaves, about 2Lt),
- wash it with kerosene (discard the kerosene),
- basify with ammonia (?will precipitate? can be filtered/collected?)
- ? extract with kerosene and evaporate kerosene ?

I will post the first results as i get the leaves,

in the meantime any help or suggestion would be appreciated,

thank you
