1 - Mix powder mimosa with 1 part calcium hydroxide.
2 - Add enough water to make it wet and mix. It should be like wet clay. (This freebases the DMT)
3 - Spread it out and let it dry completely.
4 - Dissolve it in acetone and filter out the solids. (Freebase DMT and other junk dissolves into the acetone)
5 - Saturate the acetone with fumaric acid.
6 - DMT fumarate precipitates out of the acetone. (Some other junk might also precipitate out the first time)
7 - Mix DMT fumarate with 1 part calcium hydroxide.
8 - Add enough water to make it wet and mix. (Freebase the DMT again)
9 - Spread it out and let it dry completely.
10- Dissolve it in acetone and filter out the solids. (At this point only alkaloids like DMT should dissolve)
11- Evaporate the acetone to get nearly pure freebase DMT.

1) acid extraction of MHRB. Your acid is FUMARIC ACID, so you convert all dmt to fumarate salt
2) boil down the extracts to a very very low volume.
3) add excess of acetone and cause precipitation of fumaric acid and DMT fumarate
4) collect precipitate and freebase it

1) extract MHRB with acetone and filter off all pieces. (soxhlet should work miracles here)
2) (optional)evap to a managable volume.
3) add excess fumaric acid.
4) see the beautiful precipitate falling.
5) freebase it

I think Noman tried an acetone extraction of mhrb with no results. 'Well that didn't work a shit' is the thread/post.

That was an extrraction from straight bark - not bark treated with calcium hydroxide.

This all looks promising, looks like my friend has a lot of work ahead.

1 Soxhlet extract 100 grams of mimosa with 700 ml 91% IPA and 10 ml 30% HCl solution for 10 hours.
2 Filter IPA.
3 Boil down to 25-50 ml.
4 Add 450 ml water.
5 Add 35 grams of salt and mix well.
6 Filter out the precipitates containing DMT HCl and some other gunk.

Hi all,

SWIM's FOAF would like to share his experimental observations on novel ways of spice acquisition. In a way it is a follow-up from the ceased dmt-nexus forum where similar discussions were held. SWIM's FOAF has been able to extract dmt from MHRB using just water, acetone, citric acid, fumaric acid and sodium carbonate. The purpose of sharing such experimental results is immensely useful because they can build platforms onto which others may be able to add ideas and (hopefully!) resulting in faster, more efficient, more clean, and more eco-friendly teks.

The purely imaginary method described below does work, but it works really really slow. SWIM's FOAF was able to extract ~100mg freebase alkaloids from 10g of MHRB. This method does not discriminate between the alkaloids that are extracted (j.spice, d., d-Noxide etc etc), this is however a subject of discussion.

The tek:

1) dissolve 5g of citric acid per 100ml acetone

2) take the shredded/powdered bark and cover it with enough citric acid acetone. Incubate in a warm place, gently agitating every so often. After 2-3 hours, filter off the citric-acid saturated acetone extract and set aside (this solution should have acquired the dark reddish colour of MHRB). Repeat 2 more times.

3) saturate acetone with fumaric acid. Acetone can hold ~20mg/ml fumaric acid if let for a day or so to completely dissolve.

4) Add the fumaric acid-saturated acetone in the citric acid-saturated acetone MHRB extract. One cannot put too much.

5) Set it aside and wait for 2-3 days. One should see a yellowish precipitate on the bottom.

NOTE: In step 2 one is making an acetone extraction and at the same time converting the alkaloids their citrate salt. After addition of the fumaric acid-saturated acetone in step 4, there is an interconversion of alkaloid-citrate to alkaloid-fumarate salt, like:

dmt-citrate + fumaric acid <-> dmt-fumarate + citric acid

citric acid has a pKa of 3.13, while fumaric acid's pka is 3.43. Fumaric acid is a weaker acid and thus in the above reaction one should have most of the dmt as a citrate salt and just a tiny amount as a fumarate salt. dmt-fumarate however is totally insoluble in acetone (while dmt-citrate is perfectly soluble), and it precipitates as soon as it forms. The insolubility of dmt-fumarate acts therefore as a "sink" and given time all of the dmt-citrate will eventually convert to dmt-fumarate and precipitate out.

6) wash the precipitated fumarate salts with acetone, then take them out and let them dry.

7) dissolve the alkaloid-fumarate salts in 5ml of tap water, then and then add saturated sodium carbonate to make the solution basic. The alkaloids will be freebased and the solution will become milky. In 3 days they will precipitate out forming nice needle-like crystal in the basic solution. At this stage, one can filter the solution (nasty procedure since the crystals tend to be sticky and waxy) and retrieve any left alkaloids by dissolving them in acetone.

8 ) Let the crystals dry, wash them with acetone (it removes any traces of sodium corbonate which is totally insoluble in acetone), evaporate the acetone and enjoy the product.

For the FOAF of SWIM 30mg were for a good STRONG experience.

Control: If no fumaric-acid saturated acetone is added in the citric-acid saturated acetone extract (step 4) NO precipitates are seen after 3-4 days. This suggests that the precipitates are the fumarate salt of "some kind" of alkaloid.

Considerations:

1) In a pilot experiment of SWIM's FOAF just acetone was ued for the initial MHRB extraction. Addition of fumaric acid saturated acetone did not produce any precipitates immediately and on the other hand this silly guy did not wait for few days to see if anything precipitates.

2) Step 7 can be tricky. Sane humans would most likely go for an already tested A/B extraction using small quantities of a NP solvent.

3) this method definitely takes ages; it relies on the acetone insolubility of the alkaloids' fumarate salts. The rate limiting step is the conversion of alkaloid-citrate to alkaloid-fumarate. This problem could be overcome IF one was using an acid weaker than fumaric acid. This acid must be available in relatively anhydrous form (like the case of citrc and fumaric acids) and must be dissolvable in acetone. A good candidate could be glacial acetic acid (=100% acetic acid) since it has a pKa of 4.75 and is therefore weaker than fumaric acid. But not everybody can get glacial acetic acid easily (as opposed to teh other chemicals used in this method).....

Any suggestions / corrections and improvements are more than welcome!

7 - Mix DMT fumarate with 1 part calcium hydroxide.
8 - Add enough water to make it wet and mix. (Freebase the DMT again)

Sweet! What brand of acetone are you using? What brand of sodium carbonate you using bro? Arm and Hammer ?
Ive been wondering how good acetone would pull from a sod carb base mix,... So the spice was in salt form before you you based it, right? Bravo my man. Is there a reason for using 5-10mL distilled water ensted of acetone to make the base solution?

This resulted in a mixture of the freebase crystals, any residual sodium carbonate AND sodium fumarate! SWIM's FOAF then washed this residue with acetone to get the freebase out and noticed that the undissolved residue was of brownish nature. At this point he assumed that it could be 1) the sodium fumarate itself (unlike, since sodium fumarate is white)? 2) some impurity that was absorbed onto the sodium carbonate and sodium fumarate?

Who knows? but washing this brown residue with more amounts of acetone did not yield any more freebase, he therefore concluded that it might be some impurity that was captured. But the jury is still out there!
