Yes indeed it simply looks like it still works. Yields of 1-3 % are also quite in the expectation range. That one report in the internet which is commonly cited with 6 % seems a little odd, not sure if thats more of an oddity.
Still quite sure that this is also true! So at least some Bufotenin could very likely get Bufotenate'd :twisted: Maybe NH3 / NH4OH could be an alternative, but if I remember correctly it was not enough to fully freebase a DMT solution once, so I lost something back there ...
Organic amine bases which magically would sit somewhere in the suitable pKb range are bad, as they will be not removable ...
Good call on your thoughts about Ethyl Acetate. I was worried when seeing you can crash out Bufo Benzoate from Aceton, that this reaction might not be running at 100 %. Solubility of any other Tryptamine-Benzoate is really high in Aceton. So naturally I would expect even IF you get Bufo Benzoate crystals, still a good amount might be hiding in the Aceton. With EA it would not happen pretty surely.
In general it would be cool if DMT-" and 5-MeO-DMT-Benzoate would stay dissolved in Aceton and/or EA. Because then you would not even need to do a hot Naphtha boil at the beginning.
Normally people might think, why exclude these? But at least for Freebase, removing them would be important for crystallization, but anyways on top their content is probably anyways always reeeeaaally low. Only for Yopo isntead of Cebil might be bigger. So when even doing the job of getting those seeds, you would probably prefer going to pure Bufo anyways. Plus it has the benefit that you can much better control your dosage, if no 5-MeO is present.
So the ideal new TEK might look like this:
Grind seeds to powder
Mix with Na2CO3
Extract with (boiling) Aceton/EA
Add Benzoic Acid, put into Freezer
= done (also wash crystals of course, optional = REX in suitable NPS, first try Xylene, then EA, then IPA)
The amount of steps here would be exceptionally low compared to original TEK
No defat needed, because fats will stay in Aceton upon adding the Benzoic. But if you say pull from a Paste similar to CIELO, it might not work too well, because Na2CO3 will be sticky and not like the Ca(OH)2 in CIELO. But then if you use Ca(OH)2 you might will probably overshoot with pH. Another consideration should be: In CIELO you found the water content being perfect for later crystallization. But with Benzoic Acid any water will be a big problem, so you would need to totally dry your Aceton/EA before salting.
Other than this the Philosophy behind CIELO truly should be adapted to as many TEKs as possible :d Direct precipitation of a salt from the pulls is much better than anything comparable. Just finding the suitable salt-NPS pair is the task ... I'm astonished that it works for Bufo Benzoate in Aceton actually, as _Trip_ found out.
Just a small disclaimer: At least I commonly write BUFO for Bufotenin, maybe that could create confusion, as 5-MeO is commonly called Bufo in spanish communitys, as you derive it from the Toad / Bufo.
