Solvent clean up

Hey fellow nexians :D

I recycle my naphta, this batch has been through at least 4 extractions and one of the problems it is that it has turned yellowish. <picked up some oils or whatever... the other problem is that i know i have there some DMT that has not freeze precip yet, but i can´t seem to extract it. I´ve tried to do another freeze precip but the naphta just turns clowdy and with this thin layer of white sediment at the bottom. The sediment does not crystalize so it´s impossible for me to get it out :?
Any ideas on what i should do to clean up my naphta and get all the goodies out? Preferably without evaping...

Thank u all in advance

salt out from the naphtha with an acidic solution, and then either re-base and re-extract or dry the acidic solution, make paste with sodium carb and pull with IPA or acetone.

Or evap your naphtha to a quarter of the amount and freeze again (but then you're losing solvent, of course..)

Or just reuse as-is for more pulls and your dmt wont be lost, it will just be added to the other dmt you extract.

why shouldnt it be yellow? yellow naphtha after pulling is very normal. It means its picking up alkaloids as well as maybe a bit of plant oils. You can do a sodium carb wash, yes... but it should be perfectly fine as it is, just freeze precipitate it.

Salting is a good solution, but isn't it cause a product loss after all? How can I know that all dmt from naphta turn into the acidic water? How much time it takes?

I thought that naphta turns yellow cos of oils and fats, is that right?

it will cause no loss at all. In an acidic solution all dmt will be in salt form and therefore water soluble. It will migrate immediately to the water layer as you mix it. Do 3 pulls, just mix well and let it separate, and you can be at ease because all your dmt will be there :D (and if you anyways reuse your naphtha, if there is dmt left in it, it will just be added to the next extraction when you pull with it)

and yes naphtha can turn yellow from oils but freeze precipitating should prevent most of them from precipitating anyways.. and you can always recrystalize it afterwards if its too oily product.

and also, oils are no problem, they wont kill ya :D they might even make vaporization more effective by protecting dmt from heat. Though they might also taste a bit harsher.

Ok thx. I was afraid that such yellow goo might contain NaOH, naphta or something toxic. But now I guess proper cleaning and evaping will clean it from this.

You cant have NaOH unless you made sloppy separation, because its not soluble at all in non-polar solvent. But even if you did, NaOH does not vaporize at temperatures reached by the lighter. If its there, it could theoretically come across as unvaporized particles, but smoking in a water bong would prevent it from ever reaching you. Or just make a sodium carb wash to remove it. Or recrystalize your final product.

Its possible there are traces of naphtha in your final product, even if its crystals and not yellow goo.. Thats why its important to thoroughly dry it. And even better, redissolve your final product in a less toxic solvent (like non-denatured pure alcohol/IPA/acetone) and let it evap again, which will release the naphtha, giving it more time to evaporate, so getting rid of any traces of it.

You can also start researching into food-grade non-polar solvents like limonene (check BLAB tek, or amorfati's non-toxic approach, or q21's tek, all in the Nexus wiki)

And what "something toxic" can there be? What you put in, you get out, so unless you added something else toxic there, there will be nothing else toxic :)

Thanks endlessness

I think i´ll go with evap and then freeze precip and then move on to buying some more naphta... This one has really paid for itself with all the pulls it did :p maybe it´s time to get a new one to do the job.

Better not. Some people do, but according to the Merck Index, sodium bicarbonate only raises the pH to less than 9. DMT's pKa is 8,68, which means at this pH, only 50% of dmt will be in freebase form (the rest being in water soluble water form, so you might lose some yield in sodium bicarb wash).

Its not so simple though because this is a theoretical calculation of dmt in an acqueous solution at a certain pH to begin with, but we are actually talking about a wash of a solvent containing dmt already in freebase form... but still, its possible some yield is lost with sodium bicarb wash, so better do with carbonate.

Sodium carbonate in acqueous solution raises the pH to 11.6, and as you can see in freebase percentage calculator at this pH 99.88% of dmt will be in freebase form, so you wont be losing any yield.

And anyways you can make sodium carbonate from sodium bicarbonate very very easily, just put it in the oven, as described in the sodium bicarb to carb conversion wiki

Ok, many thanks. I'll going to buy some sodium carb and IPA tommorow. Unfortunatelly I've already done 2x sodium bicarb wash, cos I haven't got carbonate right now. The naphta looks a way better now but still yellow. I already took it in the freezer, expect some crystals tommorow.

why buy carbonate? I just linked you how to make your bicarb into carbonate....

Why not? It's cheap, and anyway I'm going to buy IPA, NaOH and naphta there aswell. But anyway thx for help, I'll definately try to make carbonate from bicarbobate.

in other words baking soda only gets half the goodies.
