Solubility freebase DMT in Heptane-Hexane

[pitubo]

I guess I should perform a verification of my own before making strong statements.

Nevertheless, temperature obviously is a factor in the solubility, or elso freeze precipitation would not work. Another factor is the composition of the naphtha. I believe that shorter chained, lower boiling hexanes dissolve less dmt at a given temperature than longer chained heptane and octanes.

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.

Melted or dissolved?

I've gotten naphtha as close to boiling as you can and I'm quite sure you can't dissolve 10-17g (your earlier range) of DMT in 60-100ml of any of the brands of naphtha I used.

Ive tested myself with hexane, heptane, and C5-C8 Naphtha in many different occasions, the solubility is of 1g/30ml at 40-50c. We got hundreds of people having the same experience here.

We also got a scientific experiment in a phd thesis posted right in this thread saying 30g/l solubility = 1g/33.3ml at 40c which goes in accordance to what our experiments show.

For you to be getting 10-17g in 60-100ml (that sounds like a huge variation and not very accurate measurement), that would be at least 3g/30ml (three time as much as we experimentally see) and at most 10g/35ml ( which is 10x as much as our experiments show)

My hypothesis is either you havent made proper careful measurements, or you are confounding melting with dissolving, or your solvent has aromatics mixed in.

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

Only when I tried to dissolve 12grams into 50mL did that happen to me.

Dissolved*
Sorry.
Interesting. I wouldn't state I did it, if I had in fact not. I did dissolve 10.2grams into 70mL last time because it was a bit hesitant to get the clear goo at the bottom back into the solvent when I had only 60mL in my recrystallization vessel. So it varies but I will say I do not know every factor that could be involved, I just know of temperature being a big component of solubility.

I'd be interested to know what grade of naphtha you used. IME heavier naphtha is a better solvent - it can reach higher temperatures without evaporating, for one thing - so would you say your naphtha was leaning more towards white spirit than light petroleum ether?

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

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

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.

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

Depends on the reason for it being yellow. If its oils/impurities then yes it will make it white as the driven snow after cleaning. If its oxides im not sure it will help. Depends how oxydized it is. But when i FASA outa xylene from the start its always white, now whith Acacia it depends on nmt content.

...If its oxides im not sure it will help. Depends how oxydized it is...

Pulling with naphtha does not pick up oxidizedDMT easily. One has to make the naphtha very warm (really hot) and lean (new) to pick up dmt-oxide. One could say that naphtha in normal pulling conditions will not pull those oxides.

Yet most cheap naphtha's (where I live) contain potential e.g. 2 % of cyclic molecules (aromatics), it is possible for this % to take onto the oxidizedDeems nonetheless. That tiny part will not crystallize and might lead to some yellow oil on your crystals. More pure naphtha's (aliphatic with near zero aromatics ) might pull whiter. I've never done a side by side comparison though, I actually don't care having that ultra active yellow dynamite.

Blessed be.

Good info,thanks.
