So I did a little pilot run with what seemed to be a pretty solid idea.

Those of us who have used A.C. know that it contains a lot of junk and other alkaloids and tannins as compared to M.H. This is what I have found to be surprisingly useful. The good news is that it also will completely remove any residual NMT, if you desire to do so. Keep some of that goo on hand, but what dirty crystals you have that weren't integrated into the goo has no reason not to be cleaned up.

Forgive me if this is more common knowledge, but I feel that it builds on what we already know about purification, because I ended up with snow white, fluffy fun with about 10 minutes' effort, plus a little freezer time which was no inconvenience because I was sleeping while it froze.
I awoke to what almost seemed to be more DMT than I originally put in.
But enough about that; here's my method:

REAGENTS:
Sodium Hydroxide
Citric Acid
Naphtha

METHOD:
First make a warm water bath for your naphta and slowly add your impure DMT into the naphtha. Remember that only a little will do the trick.

Second, mix a small amount of aqueous citric acid. Make sure to use enough to make the solution taste like lemon water. This is basically what it is.

Third, add the aqueous solution to the dissolved spicy naphtha and in some vessel or other give it a very vigorous shake. Don't worry about the emulsion, it will settle almost immediately. Allow this to cool so all of the citrate precipitates, because DMT is temperature dependent, assuming all of the DMT did not react and precipitate. When it is cool, agitate again.

Fourth, separate the aqueous citric acid which now contains DMT citrate, insoluble in naphtha. Use the naphtha for more extraction or discard it. If you've gotten this far, you know what the most prudent choice is already.

Fifth, add some sodium hydroxide until you achieve the necessary pH 12+. Too much won't hurt, but you don't want to be wasteful either. All of the contaminants are in the old naphtha which should be yellowish, containing all of your tannins and fats and oils and whatnot, as well as environmental pollutants.

Sixth, add a measure of warm naphtha at your discretion, preferably enough to make a layer on a pyrex dish, to your aqueous NaOH solution, which will also be very warm due to the exothermic reaction of the NaOH+H20, and agitate for as long as you feel is comfortable in an airtight vessel, once again, not needing to worry about emulsion or any other problems. Make sure to periodically release pressure

Separate the sodium hydroxide solution away from the naphtha, ensuring that the entire solution stays warm while separating. Dump the NaOH solution down your most clogged drain, since the stuff is originally sold to clear out drains, and let's face it, there's no sustainable, environmentally friendly way to do that. May as well put it to good use.

Retain the naphtha and place it in a pyrex dish, or if you're feeling bold, you can also use a jar, even though in my personal experience I have found that a jar is incredibly difficult to remove residual crystals from. Freeze-precipitate as usual, and if you've gotten this far, you should already well know how to do this.

If you really need help, you let the stuff freeze and forget about it for a while, preferably over-night whilst sleeping and then wake up to a beautiful clear, white naphtha with beautiful fluffy white fun floating around in the dish.
Strain the naphtha off with a separation method of choice (for me, I used a coffee filter dipped in the saturated naphtha and a funnel and jar.

Evaporate the remaining naphtha if you so desire, or add it to your extracting naphtha, or use it for another cleaning. The choice is yours, but you should never waste naphtha.

Cheers and safe travels!

You combined the normal re-x with a mini a/b and freeze precip. i never thought of combining the two. but if it works for you, sweet. i dont think the citric acid and lye are needed. have you tried just doing re-x and freeze precip by themselves? id do a side by side comparison.

I am not trying to sound like a dick or anything, but this really isn't anything new. Lextek on the wiki explains this process in detail. I would recommend that people do more than one naphtha pull on the basic solution. This would ensure that all of the DMT is recovered. Also make sure to leave the aqueous solution out uncovered for a while, to evaporate any residual naphtha before dumping it down your drain.

All that being said, I am always glad to see new members experimenting and trying to develop new techniques for extraction.

I didn't figure it was new knowledge.

And also good looking out adding the second naphtha pull. Didn't occur to me, and I thought I was coming out a little light... I figured I just lost a lot of mass from impurities falling off.

I mean this method makes perfect sense though... You remove the "impurities" of the plant by doing an acid-base extraction first and foremost, so it would stand to reason that you could get rid of more junk by washing in this manner.

whats wrong with dumping naptha down the drain?

I believe it can degrade certain kinds of metal and PVC, which plumbing is often made from.


Yea I have integrated this method into past ACRB extractions (basically an A/B/A/B extraction), and always yielded nice fluffy white crystals. Once I had my DMT and impurities in naphtha I would salt 3x with a couple hundred mL of pH 4 water, then combine the saltings and pull 3x with minimal naphtha.
