SWIM told me he's dreamed of doing naphtha extractions, but wants to dream of d-limolene ones. Unfortunately, the teks here are inconsistent in regards to the amount of solvent per pull per amount of MHRB bark:
https://wiki.dmt-nexus.m..._-_The_Big_Leisurely_A/B
https://wiki.dmt-nexus.m...nd_Fumaric_Acid_Approach
The d-limonene to bark ratio of these two teks differs by a factor of 5!
Additionally, if one is dreaming of one of the teks that salt the acid solution prior to basifying, and thus expect that more alkaloids would be pushed into the solvent, by how much would the d-limolene need to be increased then?

As an aside, if dreaming of using a DIY magnetic stirrer, how much could time per pull be shortened?

They are extracting from different amounts of solution which is the main factor in calculating the amount of solvent to use.
A ball park guess would be

1l of solution from A/B 50-75ml/pull (4 will probably get the vast majority out)
2l 100-150/pull
3l 250-300/pull

d-limo pulls very well especially when warmed slightly so you probably wouldnt need as many pulls as when using naptha.

If you choose cybs tek you can just use the same volume of d-limo as naptha then just backsalt as per earthwalkers method..

Thanks for the reply. SWIM dreamt of 3x acid, 45 min boils, of 50 g MHRB, for a total of half liter tea. Defatted once only with 35 mL d-limolene, as MHRB has very low fat, salted, basified, and pulling 5x the resultant 0.6 L with each pull 35 mL d-limolene for 45 min, with interspersed mixings, except the last one left overnight. Will be interesting to see the yield at the end of the dream.

Some nights ago SWIM dreamt of extracting harmine and harmaline from rue, and SWIM wonders whether it's best to vape that together with the DMT, or before it, and how much earlier.

For 50g cybs hybrid acid-base tek is ideal and substitute d-limo for naptha keeping with the same volume and pulls of solvent. https://wiki.dmt-nexus.m...ybrid_ATB_%27Salt%27_Tek How do you plan on extracting the freebase from the d-limo? You will have to backsalt/mini-acid base it so a defat at the beginning isnt neccessary as the the back salt will be separating the plant oils from the spice.
You smoke the harmalas before and/or during, plenty of info on the forum about it.
The nexus is a no SWIMMING zone by the way It wouldnt stand up in court.

What if the person in question quite literally is a SWIM? ;p

I wonder why you suggest to use the same amount of d-limonene when DMT solubility in it is supposed to be higher than in naphtha?

Looking at FASW. Fairly high purity FA is cheap on eBay. I assume DMT fumarate is directly consumable for pharmahuasca, if one decides to go that route instead of smoking it?

Thanks

P.S. I don't know if there's an issue with the forum software, or my thread got moved (I thought I had initially posted in the WELCOME AREA but not the FAQ subforum), but the link to the thread from my subscriptions page is not working--it shows up as a non-link and I had to search for this thread with Google...

Like I said its the size of the solution that is the main factor,and also as I mentioned you probably wont need as many pulls as when using naptha.
You assume correct, and it can be easily converted to freebase via paste and pull when/if desired.

The teks note that excess fumaric acid can be removed by dissolving the dried out product in minimum water, leaving most of the low-solubility FA behind.

Is this step necessary if the DMT fumarate is to be freebased? I assume the result of having FA as an impurity when reacting with sodium carbonate would result in sodium fumarate after freebasing. Is this not also the byproduct of freebasing the DMT fumarate? Or is that something else? If the former, then there'd be certainly no need to separate leftover FA from the product before freebasing, unless accurate measurements of yield are required.

Yeah thats right its not neccessary to remove the excess FA if freebasing as it will get neautralized.
Sodium fumarate isnt a bi-product of freebasing as it will get neutralized due to the alkaline solution and will release CO2 hence the fizzing/bubbling during the reaction.

1 g fumarate from 50 g MHRB. But what is the freebase content per given amount of fumarate? I've found one mention of 2/3 when searching, but I'm hoping to confirm that number.

When trying to freebase a small portion of the fumarate using the dry method (wet paste with sodium carbonate, then dry with anhydrous magensium sulfate, and pull with anhydrous acetone), the following problem is experienced: lower than expected yield, and no crystals but an orange oil. Can't be plant oils and waxes content, as starting material was MHRB and even a small defatting step was used. Any suggestions? Would slow freezer crystallization from the acetone work better for both yield and solidity?

Should be potent! Its full spec extract so probably has a bit extra in there stopping crystallization.
USing acetone can produce oil as it evaporates so fast. It might solidify if you leave it out.
You cant freeze precip with acetone. Maybe do some more pulls on the paste there could be more in there.
Anhydrous IPA is better for a solid extract. You could even dissolve the oil into some IPA and leave it evaporate slowly.
