Hi there,

Today I tried using FASA to recover dmt from my xylene pulls but I still can't see any solids precipitating out of my solution. Now that I read more about acetone I realised I might have used regular hardware store acetone instead of anhydrous acetone to prepare the FASA. Is there anything I can do in this type of situation?

Thanks in advance,
Donald

How long has it been sinc you added FASA? It may take days for precipitation.

If your acetone has water, what would probably happen is some goo forming on the bottom of the container, where at least some of your alkaloids will be trapped (together with other plant impurities/trace alkaloids).

Worse comes worse and if after a week or two you dont have a significant amount of alkaloids precipitated, just wash your xylene with FASW (or just with water since you already added fumaric acid with acetone), separate the bottom layer and evap it. That will have your alkaloids + some impurities. Then you can proceed to purification (read sticky for cleaning fumarates in fumaric acid subforum)

Good luck and let us know how it goes

Thanks for quick response! It's good to know that it could take that long time, I was getting worried already (perhaps it should be mentioned in the wiki as well.) It's been about 17 hours when I started adding FASA over 8 hour period. I've let it sit 7 hours overnite and now it looks like there are very small amounts of something stuck at the edges of the container bottom.

Hopefully there will be more, I'll see how it goes. Should I be adding any more FASA at this point?

You can add more FASA and if it clouds more, keep adding. Otherwise just let it stand and come back in some days. Let us know how it turns out

You can also check the MSDS for the brand of acetone you bought to determine whether or not it is, in fact, anhydrous. Just google "(your brand) acetone MSDS".

I couldn't find the MSDS of this certain brand of acetone but I decided to use it for the rest of extraction. On the side of the can it says 100% acetone, not sure if it assures it's anhydrous though.

Today I checked what FASA had managed to do and the container of first pull had quite nice looking red jungle alkaloids stuck at sides and a white cloud of dmt-fumarate (?) on the bottom. I carefully decanted the xylene, scraped off everything I could from the containers and dried it. Result in first attached picture.

I proceed with this tek to convert fumarates to freebase. I think the yield from the pulls were ~1.1g and I began following the tek. My alkaloids didn't look nearly as crystalish as in the tek's pictures though, and I'm quite unsure if it's freebase yet. How much should the weight of fumarates drop after converting them to freebase? I still have ~1,1g of product and there's a picture of it as the second attachment.

Is it worth/safe to try to smoke it at this point? Should I do more acetone mixing steps as in the tek even I already did three? At least it smells like spice to me so perhaps nothing has gone terribly wrong at least.

You "think" it was 1.1g or you're sure it was 1.1g before? Because if you just think, well, maybe you remember wrong aand all is fine, you did lose the 30% weight which should be lost in the conversion. If you do remember right and its the exact same weight, something is wrong.


Did you make paste wth sodium carbonate, adding water and then letting it dry after mixing, before pulling? If you didnt add water, it possibly didnt freebase it, and if you didnt let it dry perfectly, your solvent probably carried over some inactive sodium fumarate (formed from reacting the fumaric acid attached to DMT + sodium carbonate), as well as sodium carbonate, which would be responsible for your extra weight.

If you put that DMT in a spoon and use a bit of heat from a lighter udnerneath, if it all melts very quickly, its probably all DMT freebase.. If something doesnt melt or none of it melts or it takes a lot of heat, its either unconverted dmt fumarate and/or some of the mentioned salts which have high boiling point.

If your acetone is dry, it should not dissolve sodium fumarate nor sodium carbonate, so you could just pull with it, filter/decant away frm undissolved stuff, and evap. Or you could use a bit of water (or better, dilute sodium carbonate solution) which would dissolve those two mentioned salts and would leave dmt freebase undissolved behind. Either way, dont throw anything away

I just realised this might be sodium- carbonate/fumarate themselves that I'm holding... Silly me, what was I thinking. The smell of spice in this powder must just be my sensitive nose.

The good news is that I saved those acetone pulls. I'll evap them and report how it goes. Thanks again!

Alright, the acetone evaporated quite quickly and left behind this reddish 'syrup'. It doesn't look like wax to me and I really can't tell if it's evapping any more. It kinda reminds me of 'jimjam' dmt pictures I've seen somewhere.

Should it evaporate more but very slowly or how am I supposed to store or measure it?

How did you realize that it is not DMT freebase, did yu do the tests I mentioned?

If all else fails, you can always just put everything together, dissolve in vinegar, filter, add base, pull with non-polr solvent, evap/freeze. Or you can put everything together with a bunch of sodium carbonate, add water to make paste and mix, let it dry, pull with acetone, evap. Then dissolve that in acetone, add FASA to precipitate fumarates, and start again

Well if I got this correct, when one is converting fumarates to freebase with the tek above, they are supposed to save those acetone pulls and evap them to get the freebase. What I first did was pull with acetone and did't realise that those pulls actually contained the dmt and dumped them into another container just in case. Then I saved what was left on the bottom of the container where I pulled from (aka the powder in second picture)

Hopefully it goes like this or I'm totally confused here
