I extracted with A/B method of the handbook. I put the benzinum (naptha) into the freezer for 12h and nice crystals started to grow in the petri dish. After removal of the liquid solvent with a syringe I put the Petri dishes upside down back in the freezer for 15 min and removed the solvent which was dripping of the crystals. Then I wanted to scratch the crystalls together but they dissolved to a slightly yellow oily liquid. I put one Petri for about 4h on top of my heater and small crystalls formed. But there is still oily liquid and the ammount of crystalls is really nothing at all.

I read in some Threads it might be N-DMT or DMT oxide but some threads also say yellow goo is DMT with lots of impurities so I'm a little bit confused what I should do now.

UPDATE: I scratched around with a razorbalde and the oily stuff imediately got white, but all 4 dishes had a yield of around 1gr that means 0,1% of 1kg MHRB that seems to be a mini yield (I think normal is 0,5-2%). And it doesn't even look very clean (so there will be more loss). I reduced the solvent which I had removed earlier with the syringe again. Atm I'm freezing it and I hope I will get some more DMT out of it

A review of the A/B extraction:

1)
I started with 1kg MHRB powder cooked it in PH3 water (HCL+H2O) for 1,5h three times. The first time I used not enough water, some bark powder burnt on the bottom and a big foamy layer was building on top (it was very slowly cooking, 1 burb per 30sec). Thus I added more water to the second and the third pull, unfortunately it didn't cook. It was just steaming a little bit but no bubbles (I think it maybe had 40-80 degrees but can't tell it for shure). The result was around 3-4l of reddish strong smelling liquid. This liquid I allowed to rest for a night and decanted it in the next morning.

2) I reduced the liquid to around 1/2l-1l and basified it to PH12 or higher. It turned black but seemed not very oily but oily. Because I had do interrupt the process I reheated it before adding the benzinum. Maybe it wasn't warm enough that's why I decide to reheat it before the second benzinum pull. This time it seemed to be too hot because the benzinum did evaporate while shaking (Maybe that was the mistake I read to much heat extracts impurities). But I added more benzinum and finished the second and a third pull. I used approximately 800ml of benzinum and seperated around 500ml (I think the rest did evaporate). Between the second and the third pull I cleaned the seperatory funnel with water because the walls were not clear enough to figure out exactly where to stop seperating. With the third pull there also formed some salts or crystalls in it but it was kind of a emulsion around it, so I heatet the benzinum in the third pull and added the warm benzinum because I thought it migh be already DMT and I didn't want to waste anything. The emulsion/crystalls dissolved and I could finish the third pull.

3) I reduce the benzinum to about 100-200ml and filled it into 4 petri dishes. These 4 petri dishes I put for 12h into the freezer the rest can be read above.

I rescued the bark from the trashcan (I dumped it, packed in to layers ziplock and a bag, so everything is well clean). Unfortunately I flushed the black MHRB PH12 solution down the drain (Wasn't shure if the HDPE container is tight). So if anything would have failed in the cooking process there would be still a chance to rscue s.th.... So my question is which tek would you recommend for extracting rests out of the bark. I thought about a stb tek because so rests of the bark powder could be breaked up and also no heat is required in the first place.

I decided to do a second extraction with Nomans Tek but I've a few questions left:

1) Can I decant between step 3 and 4 or does it influence the result? because I think it is easier when removing the powder to seperate and I could imagine the powder gets stuck in the seperatory funnel.

2) There is 1gr Iye recommended in the Tek but my bark is also acidic from the previous A/B Tek cooking and I just have around 800gr of Iye left, so will it work?

3) Do you think the second extraction with STB will give me any extra results or is it just a waste of time because I propably messed up some where else (not in the acid cooking process) in my A/B?

4) How can I get shure, that there is no more Iye left?

5) Why does STB work. I mean in A/B there is always written that DMT is not soluble in high PH, so why does this work at all?

I extracted the MHRB again with Nomans Tek.

I added about 850gr of Iye to 3l of water after cooling down the solution to approx. 40 deg Celsius I added the bark (maybe 700-800gr) and shook it like crazy. After an hour I put the solution through a strainer.I did four pulls with around 200ml of benzinum in every pull. The first three pulls I shook hard, let them rest for a while and then gently moved the container upside down. I seperated the layers (no emulsions had formed). I reduced the benzinum to around 200ml and freeze prep. it. I did evaporate the remaining benzinum after the freeze prep. The result was another 1,6 gr in whole it has been a yield of about 2,6 gr that's 0,26 % yield and it's not even recrystallized. Seems a little bit too less.

Was the bark of bad quality or which steps could gone wrong? What I did notice that after reducing it there where already falling out a lot of snow crystalls at room temperature. I reheated the benzinum to dissolve them again that all the stuff in the flasks would go over into the dishes where I made my freeze prep. and my feeling was that there have been more crystalls already in the flask at room temperature then after the freezer. So could it be that if I reduce the benzinum too much that the DMT evaporates?

If you do an STB, dont strain the solution, leave your mimosa with the solution.

Is the bark from reputable supplier?

Also read the FAQ, instead of shaking hard once per pull, better do several cycles of stirring/letting stand, over a couple of hours per pull, to get more alkaloids. Also 4 pulls might not be enough with naphtha, do another couple of warm pulls (warming in water bath, no fire!), and mix them over a few days each, pre-evap and freeze, see if you get more.

And no if you dont reduce naphtha with heat over 100c, then there should be no dmt evaporating (though some n-oxide might form, better just evap at room temperature or just warm, not very hot)

I did a few shakes, ok but next time I will let it sit for a some more time, I thought this wouldn't effect it much because the layers are separating pretty quickly (5-7min and nearly all of the benzinum is on the top). Perhaps I try to reduce it more after the acidic cooking process so that I can use my magentic stirrer to let it stirr for a few hours. Reducing more because I think the stirrer can't handle more than 500ml-1l, so that I will get 1l in whole (Acidic Solution + NaOH Solution and Benzinum). Is there some limit how much one can reduce the solution (OK STB it will get a slurry liquid but A/B i think you can reduce it a lot). Or how dangerous is it to add the NAOH directly to the acidic solution (very gently and with precaution of spits).

The bark is from Phyto***** it seems to be new supplier couldn't find a lot on the nexus about this supplier.

Not sure about the supplier

Yeah a/b you can reduce quite a lot, but 1kg in 800ml sounds like too little, im not sure.... maybe you can do in two runs

and yeah its more important to mix and let it stand, a few times, then to mix less times and let it stand for longer, ime
