Hi there,

someone knows how much dmt freebase can be dissolved in 100mL of heptane and\or hexane?

i want to try some assay of cristalization...
and i did not find nothing about solubility of dmtfreebase in hexane or heptane, only water..
there is any chemist that can help me with this?

ty

I was once able to dissolve about 200-300 mg of DMT freebase in 10-30 ml of warm heptane (sorry, don't remember actual amounts).

When the heptane cooled down, the solution turned milky and some precipitates appeared when in contact with cold glass. This should have been close to solubility limit.

You can dissolve almost 1g of DMT per 30ml warm heptane/hexane/naphtha. I recommend doing another pull on the goo that is left behind because you can still retrieve some more DMT, but freeze/evap separately since it will have a bit more of the oils

ty all..

i finally found in Alain Gaujac doctors degree..
something like little more than 30g/L at 40ºC (g dmt per L hexane)

there's a way to convert dmt fumarate to dmt freebase? where can i find?

Check if computer is ON + follow this procedure

I disolve fumarates in water then put in a jar or bottle, add lye, at which point the water goes white, then i pull with naptha, then you just precipitate as normal.

This one? Interesting thesis

What page is the solubility info you mention? I can't find by searching "solubilidade"


And yeah you can easily convert DMT fumarate to DMT freebase as linked by Jees. The method 3 that appears in the wiki link is the most fool proof IMO.

Good luck

However much dmt can be dissolved into a solvent such a naphtha or heptane is entirely dependent on the temperature of the solvent itself. I consistently have recrystallized anywhere from 10 to 17grams of deems into 60-100mL naphtha while it was just moderately warm- slightly slightly hot and all the while the deems crystals(I turn the fluff to crystalline after the first precipitate is dried and scraped) come out odorless, tasteless and transparent.

ty !
you know if this method (convert freebase to fumarate, then, convert fumarate to freebase) is the best method to clean DMT?
yellow dmt can turn white dmt after this procedure ?

anyway ill try.. ty again

im brazilian, so i can read the thesis without any problem...
there are some interesting things, like the average percentage of dmt on the 24 differents MHRB that he extracted, something between 0.12% and 0.935% ... this info you can get in the "ABSTRACT"..

the info about solubility i found on page 50 (6.2.b. Reagentes)
"O DMT bruto foi dissolvido em hexano, a 40 °C, para se obter uma
concentração aproximada de 30 g L-1"

Something like:
"DMT was dissolved in hexane at 40 ° C, to find an approximate concentration of 30 g/L"
but the thesis dont say that concentration is saturated solution..
He dissolved dmt in hexane to recristalize and purify the cristals.. So I thought it might be something close to saturation

let me see if i got it...
i can dissolve something like much dmt much dmt in hot heptane per example...
ok until here... but how can i do this magic to get the cristals all together like you did?

im not sure if i understood this piece:
"- slightly slightly hot and all the while the deems crystals(I turn the fluff to crystalline after the first precipitate is dried and scraped)"

Yea the hotter the solvent, the more dmt it can bind to it, and upon cooling, the faster it crashes out depending on how much was dissolved into the solvent.
I just posted my extraction tek and crystal recrystalization tek on the "introduction essay" part of the welcome area. Check it out there if you'd like to make crystals like these.

I declare BS. There's no way you've fully dissolved 10-17g of DMT in 60-100ml moderately warm naphtha.

Whatever you'd like to believe is fine by me.
I not only have done it, but have done it many times over.

Indeed. This does not align with my own experience nor with what I have seen reported on the nexus and in the literature. There is a recently active thread on the very subject, even.

(EDIT it's this very thread... hrmpfff.. (or did the threads get merged? -- puzzled))

LevitatingGod's numbers are off by almost an order of magnitude compared to all the other reports. But then again, LevitatingGod also advised(*) a dmt vaping dose that was off by an order of magnitude...

(*)The post was edited, but a quoted reply still has the original unedited numbers.

It's not about somebody's particular belief, it's about providing accurate and verifiable information.

Did you read my response in the "Thoughts on purity" thread at all?

I used to think I needed 30-50mL per gram until stumbling upon xcensions comment on 'growing large shards' here on nexus and he said "I heat my solvent, and use a small shallow glass dish instead of a shot glass (easier to scrape out). I only add enough solvent to dissolve the dmt, no more then JUST enough.It is not much at all, nowhere near a shot glass full for sure. Then just cover and let it sit and grow"
So I gave it a shot, and guess what? I melted 10grams into 60-70mL plenty of times. Also "moderately warm" is too vague to know for sure if we are talking about the same temperatures, as I do not test the temp ever during this stage.

Did an undissolved layer stay on the bottom of your warm solvent?
