Vovin / MaxIon gone wrong?

[isntme]

Hi all,
I did my first extraction of Brazilian MHRB from a trustworthy source (so I guess the problem is not with the RB).
I followed a combined vovin / maxIon tek (see appended flowchart).

When adding the salt I got some nasty precipitation (which I however could separate and resolve in H2O again).
I kept both fractions for curiosity.

However, overall yield is quite low (~1g, see detail in the lower right of the image); I would have expected something towards 3x1g.


I used lightbenzine / cleaning benzine - but guess this is not the problem.
Everything might have been to concentrated - but some teks state: use as less water as possible.
One point could be that I could not determine pH 12 well (dark liquid on teststripes which indicate 10 -14 with dark colors made it hard to decide where I am). So I guess I ended up above 12.

I made 2 pulls in sequence, then let the liquid rest for at least 24h, then next 2 pulls.

The increased yield in the 2nd run might be due to reuse of the NPS (it is still clear - no yellow color or so, even after the 3rd run).

What do you think?
Any hints?

Is this your first time using this batch of bark? And did you get a better yield last time?

If not, the main loss of product is likely happening during the initial filtering steps. It sounds like the bark was removed too early, and extracting it only twice without boiling may not be enough for all the DMT to migrate into the polar phase.

Additionally, increasing the volume of the non-polar solvent a bit could help improve the yield.

It was my first ever extraction, so no reference.
The bark was sitting in the acidified water for 7 hours at 50°C, and then 2 further times for 1h at 50°C. The result was clear but quite dark-red liquid
IonTek states several hours warm, not hot.

So should it be hotter or longer?

The 4th acidic extraction to polar resulted in a light red liquid, so I thought there will not be much more in the bark... (this 4th batch is still to be processed)

I wouldn’t bother with an AB for MHRB and advise you to try an STB on 50 grams of bark and see if that works better than the AB method, if you feel then after extraction that you need to clean the extract a bit then do an mini AB.

Also make sure you grind your bark very fine before using it.
Allot of members have success with this method: Cybs' Hybrid ATB 'Salt' Tek - DMT-Nexus Wiki

Good luck and don’t forget a gram of DMT goes a long way.

I finally finished to document the results from my extraction, see attached, updated figure.
I'll comment findings below.

Thanks for your hints. As far as I see when looking in Cybs' Hybrid that this is basically what I did (as combination of max-ion and vovin).
Taking into account how hard it is in my place to get MHRB, my mistake was to process all in one batch; could have done 3x50g, playing with the parameters.

Additional findings:
1) The slime might have been the result of not fully dissolved salt, so make sure it is all dissolved before adding to the MHRB solution

2) the 3rd fraction (sitting acidified for 48 h) resulted in an only light red liquid and provided a super tiny amount. Taking into account that all the advanced teks approach this step in the way I did, I guess extraction from MHRB -> acidic solution was complete

3) 7th & 8th pull did provide only a tiny amount. My thinking with having the 4 rounds with 2 pulls each, rounds separated by 1 day at least, was that if transition to freebase might be slow (to high pH?). So I wanted to see if the extractable amount 'recovers'. See e.g. 1. and 2nd round, 2nd provided more DMT, while the 2nd pull of the first round had less than both of the second round. So I guess doing 6 pulls in a row will not provide the best result.

4) recovering the substance from the used Naptha provided 0.54g brown/yellow goo, recrystallisation provided 0.3g light yellow stuff (which is fine according to this thread).
The crystals to the upper end of the shot glass have been white initially, while those at the bottom light yellow. The white ones turned yellow during drying.

Overall I achieved 1.28g, i.e., 0.85%, which is not impressive, so room for next time. But as Varallo said: 1.3g goes a long way (even when sharing with friends).
