Funny Swim was justing thinking of a way to clean out the red Naptha w/o having to just wait it out.
Swim has run into the same problem, actually just did. Swim did an "A/B" in the Naptha and no more red naptha, just nice and yellow.
This is how swim would recommend one cleaning out their red Naptha pulls, very easy and fast with nice results.

I'm wondering if washing the naphtha with clean water would get the redness out without removing any DMT, but I don't know what the appropriate volume/ph should be. Maybe washing it with very basic water might help, or maybe not. I have no idea. Noman's tek has always worked for SWIM.

I've tried a sodium carb wash and it's not very effective.

swim was wondering the same thing , it was the carb wash or the naptha "A/B" tek , swim chose randomly and went with the A/B and it works fantastically

When I was getting red naphta and doing a mini-A/B as you did, I've found that adding 2 more steps produces snowy-white spice.

1. Defat the acidic solution with naphta.
2. Settle and decant the acidic solution.

After these steps and subsequent basification, naphta pulls were so clean I was afraid there is no spice in there.

Yeah i was thinking about the defat stage & whether that would draw out some of the undesirables, i'll give it a go, can't wait for my Naphtha to arrive

1)fp red solution for 20 min,
2) decant (you will get brown sludge at the bottom)
3) fp the clear naphtha for what's left of the dmt in there
4) take the brown sludge and let it dry completely
5) pull the brown sludge with acetone or IPA a couple of times and let that evap

-> you now have fp dmt xtals in the freezer plus some nice tan spice from the IPA/acetone pulls
this yields smokeable product in both cases.

I've heard similar claims about the bicarb wash; although I was thinking more of a lye wash. From SWIM's experience, DMT crystals would rather hang out in naphtha than in pH14 water (hence the basis of every STB tek). If the mysterious red stuff would rather hang out in basic water than in naphtha when possible, then washing the naphtha 100mL water with 2-4g lye would remove the impurities. (If that red stuff is tannic acid then I bet it would rather be in water than naphtha, as long as there is enough water for it to dissolve into). If not, then following this advice would probably lead to nothing more than a mess and a loss of product.

Godspeed.

Excuse my ignorance, but what is "fp"? Is it freeze-precipitation?

Ok, so i added some vinegar to my red Naphtha and now there is 3 layers, vinegar at the bottom, a layer of white fluffy stuff (which i think is the DMT salt? hoping its not Lye) then a layer of stuff that looks like fatty Naphtha on top of that, im thinking that i should take the top layer off, discard, then re-basify & re-pull?

So its like a defat except im using the Naphtha already in there...

the layer in the middle is probably an emulsion. (dont shake!). Let it stand, you want the bottom layer.. Separate the bottom layer after emulsion is gone (or after at least most of it is gone, leave any bit of emulsion together with naphtha, dont get it). Then repeat process with more vinegar once or twice.. Then add lye to vinegar, re-extract with solvent, re-freeze.

I only stirred/swirled it in a beaker, no shaking at all, but it looks like emulsion as its bubbly, so im gonna leave it to stand now for at least an hour & then as you said i want to siphon out the bottom layer & leave the top layers in there... i also added a tad more Naphtha to do some more defatting, im kinda concerned as the white bubbly layer has gotten bigger each time i stirred it, hopefully it'll calm down after a while, i just thought i had to give it a good mix to get the DMT to come out the naptha & salt in the vinegar, now im guessing a gentle stir is enough

The emulsion didn't seem to settle at all so i took off the bottom layer of vinegar into a fresh beaker, some of the white stuff was mixed in though, i then added some lye, i didn't measure how much but enough to make sure the PH definitely went high, i added some Naphtha, stirred very gently, got loads of bubbles again, reading some teks it seems bubbles are unavoidable to an extent... so yeah, i've added some Naphtha, stirred and just letting it settle now, will siphon off, freeze & report back, fingers crossed...

The original left over fatty Naphtha from before still stank of DMT but anytime i added some vinegar & gently swirled i got loads of bubbles so there wasn't much i could do with it after 3/4 vinegar extractions

Get yourself a pH meter or some pH paper. Your basic solution should become dark brown, almost black. If your pH is high enough ~13 or more you'll have no problem with emulsion.



They are avoidable. I use a magnetic stirrer on low and there are no bubbles at all. You may close your jar hermetically and roll gently back and forth on an even surface. Even if you keep your extraction jar completely still, in time, the spice will migrate to naphta anyway.



I'd suggest to reduce your naphta before freeze-precipitation. It will increase your yield and shorten f-p time. If your pulls are not very different in color you may combine them and process all together.



Do not discard any by-products before you're finished with your extraction.

A few times I've found more spice in some unusual places.

Good luck.

yes that's it, sorry for the chat slang

I suspected that, but 20 min for fp seemed too short.

Are you referring to doing a fresh extraction of MHRB, because i was only cleaning up red naphtha, i added a lot of lye to the vinegar but it definitely didn't turn black?

Yes. Check pH of your current basic solution. What color is it?

I don't have it anymore i have yellow Naphtha which i extracted from it, it has sat in the freezer all night and done absolutely nothing... maybe i didn't add enough lye as i was using straight vinegar to clean up the red Naphtha so it must've been quite acidic, it definitely didn't turn anywhere near black when i added the lye.
I was cleaning up red naphtha not doing a full extraction, should it still have turned black?

I don't have a PH tester either...

Naphtha just seems to take forever to evap out the jar, maybe there's too much in there why no crystals formed overnight in the freezer, it definitely has a yellow tint to it...

It is a full extraction, although small-scale. All steps must have been followed, i.e.
1. Dissolve your dirty product in acidic water (pH ~4).
2. Settle/decant/filter the acidic solution.
3. Basify to pH ~12.5
4. Pull 3-5 times with a NPS
5. Reduce combined NPS pulls until it becomes cloudy.
6. Freeze-precip.

These are basic important steps. Failing to perform any of them will lead to major losses of the final product. Well, skipping step 2 will lead to dirtier spice only.



That is one of the most useful devices for any extraction. Buy some pH paper, if you cannot afford one.



How much naphta did you originally have? I do not use naphta, because I have access to Heptane, but I do not think that naphta is less volatile. Under a fan I can evap 100 ml of Heptane in 30 min. I can do it even faster by gently heating it (~40 C).

Reduce your naphta to 1/5th of the original volume or less. Watch for naphta getting cloudy. When it does, stop reducing, close your jar hermetically and put it in a fridge. In 2 hours move it to a freezer. If no crystals are formed in 6-8 hrs, your naphta is empty.



Yellow tint may be caused by plant oils. Often my NPS is completely clear, but produces very substantial yield.
