Hello, hello, hello!

Hope i've posted this in the right place, my apologies if I haven't, I've no access to post in the grown ups section yet haha… anyway,

I've been a lurker here at the nexus for quite sometime now, and found it extremely helpful and informative. There are some truly exceptional minds here!

I'm usually a typical acid/base lover, but have stumbled upon the wonderful magic of FASI. I'm looking at modifying my usual route of extraction to the following, and was wondering if thou might have some opinions for thee.

I'm working with acacias here, and usually have success with the acid/base route providing I include at least 1 defatting step. I've recently moved country, and have had to give up my sep funnel, it also seems rather hard to come by solvents which were usually easily accessible to me. So because of this, i'm back at the nexus looking for a different means of extracting my favorite spice.

I'm looking at following Q21Q21's Vinegar/Lime A/B Extraction Tek, using d-limonene as my solvent of choice, then using BLAB's FASI tek to precipitate my DMT fumarate.

From here I want to clean my DMT fumarate using boiling hot IPA, filtering and then letting the DMT precipitate as the IPA cools.

After this, i'll be using the Fumarates to Freebase Water Crystallization Conversion tek, particularly The slow pure white crystallization method (also in BLAB ).

The Tek breakdown is as follows:

(acid)
1. Pulverize DMT containing plant material
2. Add vinegar until material is wet
3. Slowly add near boiling water until it is wet enough to flow when you tip the container to one side.
4. Stir several times as the bark is let to sit for 20-40 minutes.

(base)
5. Add calcium hydroxide to obtain desired consistency (i.e.. 150g lime for every 200g material used).

(pull)
6. Pull 3X with d-limonene.

(salt)
7. Create FASI solution (saturate IPA with fumaric acid, decant from excess fumaric acid)
8. Slowly add FASI to DMT saturated d-limonene (drop wise)
9. Allow to sit until DMT fumarate crashes out
10. Decant d-limonene from DMT fumarate
11. Put d-limonene back into another container to allow excess DMT fumarate to precipitate.

(clean)
12. Dissolve DMT fumarate in boiling hot 99% IPA.
13. Filter solution
14. Place solution in Freezer over night
15. Decant IPA and dry DMT fumarate

(convert)
16. Create a sodium carbonate saturated solution (sodium carb in water)
17. Dissolve DMT fumarate in near boiling water
18. Add sodium carbonate saturated solution to DMT saturated solution (drop wise)
19. Put solution in fridge for 3-5 days
20. Scrape DMT from vessel, and dry.

From my understanding this tek should be more than effective. I would however, like to ask for your opinions on some potential changes.

1. Can the pulverized material be defatted before proceeding to acid/base. (i.e. can the material be soaked in a solvent prior to being made acidic, then decanted off, the material can then be left to dry completely to assure all solvent has been evaporated before proceeding to the next steps). I would assume this would result in less fats/ plant oils etc. being pulled in the 1st extraction after the material has been made basic.

2. Instead of going the STB route, can one proceed to soak/ cook the material in an acidic solution, decant/ filter and repeat 2 more times, combine all acidic solutions and evaporate down to a minimal amount. Once the acidic DMT saturated solution is evaporated to obtain a smaller amount, can you then add calcium hydroxide to make a paste/ crumbly mixture and proceed to pull from this (I would assume this would result in less solvent loss as there is no plant material to soak up the solvent, and only DMT containing solution + calcium hydroxide)?

I'm sure I had more questions, but am unable to think of them right now.. anyway, thanks heaps to everyone on the nexus for their amazing input, love it!


peace!

Sounds like you have a good grip on it already.

In any case I'll offer my own view:

I wouldn't defat the dry plant material, seems like you'd need tons of solvent which the plant material would trap, maybe you could decant/filter part of it but part would be absorbed/soaked.. Seems like a very innefective way of cleaning up. In fact I wouldn't defat at all since you're anyways gonna work with FASI, which precipitates the alkaloids away from the fats, that is essentially defatting and way more efficient without all this loss solvent.

Maybe it would work fine to just reduce the liquid and base that with calcium hydroxide but it sounds like potentially a problem to me. DMT is stable in acidic solution, but once you reduce the solution more and more, small particulate material starts to form in the brew. If you filter that out, you're probably losing alkaloids because it seems there's some alkaloids there (just like precipitates in reduced aya brews have alkaloids mixed in). If you dont filter and base everything together, it might be fine, but be sure to test with small amount first (and/or maybe do a side by side with another pot with the plant material mixed in with the base so you compare yields if youre up to it).

Also a couple more details, between step 6 and 7 maybe making a sodium carbonate wash is not a bad idea, or at least let it stand for a while before adding FASA so you can decant it away from any water droplet that may have come across with the limonene.

Also between steo 18-19, I've found that first leaving some hours at room temperature and later going fridge, improves crystallization.

Be well, and dont forget to tell us how it went!

PS: Feel free to write an intro essay so we can properly welcome you into the community

cheers endlessness!

yeah I thought I read somewhere that working with FASI precipitates DMT and other alks leaving behind fats etc. cheers for clearing that up for me. I'll ditch that idea, and from the sounds of it; trying to reduce the acidic solution down, seems to be a waste of time... I'm just stuck in my traditional A/B ways and looking for any way round not using a sep funnel. I'll stick to Q21Q21's Tek for now, perhaps i'll give it a go later on and compare results.

I will definitely get an intro essay together and post my outcome,

cheers for your wonderful knowledge!


peace.

Is this looking about right now? Can I please get an ID on the cutting? Thanks
