Anyone who has done STB at the kg+ level knows its a touchy bitch and a lot of work.  I found this tek here:

If you guys give me some good advice I will have my friends try it at the 5kg level and post results.

I have a few questions:
1) it says to add the base to the alcohol, I assume you add equimolar base or slightly more compared to the amount of dmt you expect to extract in order to freebase the naturally occurring salts, so 1kg should require less then 100g of base, which is nice compared to the 500+g you need for a STB.
2) some people speculate that using MeOH and NaOH you may generate sodium methoxide, which would degrade your spice, is this true? I would rather not have to worry about keeping my meoh anhydrous.  I guess an easy workaround would be to use KOH.
3) Would you have to evaporate most of the MeOH before pulling with naptha or can you leave some?  Do you have to evaporate at all after steeping and filtering?  I guess my real question is: are naptha and meoh miscible?

Let me know, thanks.

Having sadly never gotten to extract DMT due to inability to possitively identify the correct species I have envisioned it for many years now and think that this theoretical would work pretty well.

Alcohol or Acetone extraction simular to the procedure in discussion allowing a slightly basic PH at the verylest thru the use of NaOH to ensure your target comes along.
Evaporate slowly to dryness since to high heat and the already high PH could damage to many things creating variables such as Saponification of any fats creating a world of hurt later on down the road.

Once dry lower the PH with Either HCl of Acetic acid I guess would work and once again evaporate to dryness this time grinding your cake as much as possible.
A solvent boil which has not been decided upon but something to remove all or most nonpolar, non alkaloid componds. Multiple nonpolar solvents would be the best possible option assuming you are able to dry them enough to ensure nothing is lost.

At this point you have your options of cold precipitation or quite possible gassing to obtain the HCl salt which you can dry and base to make sure you have pure DMT in the nonpolar you freeze out.


This should in theory work pretty well for DMT since its effective in many alkaloid extractions.


[edit]


Yup forgot to mention that, KOH is a stronger base then NaOH meaning that the equilibrium will lay further to the right which is not what you seek in this case.

So my friend took my idea and ran with it.  He heated 2kg very finely powdered mexi mh rootbark covered with about 3L of methanol/100g NaOH at 40c for 3 hours.  Well he tried to filter it afterwards and realized that only about 10% of the solution was recoverable even with compression due to the slurry from the very fine powdered rootbark.  He added the 10% back to the rootbark and let it sit for a week or so before he mutilized an ac unit so he could perform vacuum filtration on this scale.  Well this slurry was so thick it worked even less then 10%.  He plans on evaporating the methanol from this material and using familiar methods to extract.  Moral of the story is if you try this method do not use fine powdered rootbark, use the shredded stuff.


I told my friend the speculation of freebase degrading in those conditions and it might not be worth his time removing the methanol and doing a standard "STB".  Do you guys think my friend is screwed?  Seems to me dmt freebase could survive those conditions, but I also noticed sodium methoxide could be formed which is a very strong base and could harm the freebase after a week of storage?

Yeah this cake method should only be done with shredded bark thats like pencil shavings.

So this guy I know threw 5kg in a 5 gallon bucket. Impossible to work with. Set it aside in storage unit for a month or two. Pulling tons of n-oxide now that he has time to work with it. He has no zinc powder handy, but heard aluminum may be more effective for reducing anyway. The question is must it be aluminum powder or would some soda cans be good enough? Lame first post, I know, but that's the way it goes sometimes

You might need to be careful about aldehyde formation, however as it will react (possibly) and form beta-carbolines which are not easily extracted via A/B techniques and this could lower your total alkaloid extraction yeilds...
Perhaps NaOH + other present organic substances => aldehydes? highly unlikely...

whats wrong with straight alcohol ?

Nothing wrong with it. It will work for this tek. But in many parts of the world MeOH is available in hardware store at $10/4l whereas 95% EtOH tends to be more expensive and/or difficult to acquire. Like in Canada, where 95%+ EtOH is only available from a chem suppliers. MeOH also has a lower BP, which makes its removal easier.

On DMT-nexus the "experts" moaned at me for asking about useing KOH and said it can produce some nasty side products when used to extract DMT ?

Harmala alkaloids from P:Harmala can be extracted with water .

Comments / advice please ?

The DMT Nexus is a great place with lots and lots of great info. But chemistry is not their long suit (with the exception of a very few members), so take it with a grain of salt. There is a lot of superstition being passed off as science.

Harmlas can be extracted with water and a small amount of vinaegar. You might get away with just water as the harmlas are already in salt form, but a little vinaegar is a cheap insurance policy.

Jungle spice is dmt that has been extracted with a less selective solvent than naptha, such as toluene, xylene, ether or DCM, it pulls all kinds of other stuff out of MHRB, which is why it isn't white, it isn't remotely pure. Here is a paper on the subject if you are interested.

antibody2 ....... thanks for the pdf . I read the first paragraph .Been looking for that info for ages and will put it in my collection .

It says what i had thought = that the solvent used extracted a wider range of the contents of the original material than naptha ? Thats why i was thinking water , alcohol or acetone .plus water and alcohol would be cheeper and easyer to get than other solvents .

My mates quark and charm have acsess to some DMT containing material and told me that they will try an extract with acetone . I`ll report back about their results .

As for DMT-nexus thats my opinion to . To many insecure people argueing whos tek is the best when they are mostly nearly the same . I got pissed off and left when a guy called GOD posted his "Slow food tek" = doing the whole extraction only useing a freezer , water and a coffee filter ...... and all the ego wankers started to shout and shoot at him . As far as i know non of them tested what he said and iff its true its the easyest , cheepest and most doable tek i`ve ever seen / posible  ......... would just take weeks to do .

The P.Harmala extract in the foto came from those two mates and i think it was done only with water . Could also have been with a little vinegar as they also tried that . They cant remember .

GOD was ok I had a lot of conversations with him on WD and never found him to be anything but honest.

I would say if he said it worked then it did.
