Called around, can't get VM&P naphtha locally. The one hardware store that previously stocked it recently took it off the shelves.

Can anyone make a recommendation for a clean alternative? Some searching on the forum revealed a couple different products, but there didn't seem to be any certain consensus on whether or not they were pure enough.

Bestine, rubber cement remover. Pure Heptane. Found @ Michaels art supply.

Can heptane be used in an A/B extraction as you would use naphtha? I.E. does freeze precipitation work?

Also, does heptane pull "jungle spice" alkaloids? I am going to be sharing this yield with a friend, and since will be his first time smoking DMT, I wanted to give him something more pure and traditional.

A/b works. Freeze precipitation works.

Doesn't pull jungle. Xylene/toulene does.

Heptanes the closest thing to naptha. If anything, it pulls purer than it. That's why I suggested it.

Enjoy.

Thank you very much!

Hmm. DCM (dichloromethane) seems like a very attractive option as well, especially if final product is recrystallized with heptane.

I can easily get DCM online, but is this a watched chemical? Is there any danger to ordering over the internet?

Can you source xylene or d-limo, or heptane? Not ideal but it will get the job done. DCM is easily available as well.

Having a hard time sourcing local DCM. If you could help me out at all, I would really appreciate it! =)

Keep in mind that DCM is polar, it will sink.

Why not just extract with bestine? I've always had great results this way.

Heptane(bestine) is good stuff, just expensive

While I'm sure bestine would be a perfectly suitable option, DCM has a couple advantages, as far as I understand it:

- Pulls more DMT due to higher solubility of spice in DCM, and also can penetrate cell walls of MHRB more easily.
- Pulls jungle spice as well

..DCM is very much non-polar..it's just heavier than water so it sinks, and has a greater holding capacity than napatha (= less pulls)
most hallogenated NP solvents sink to the bottom..

DCM is a different beast. it's somewhat nonpolar, but has a dipole moment, which is characteristic of polar molecules. DCM has an octane/water partition coefficient of ~1.5, so it's more polar than the aromatics. the fact that it's denser than water has little to do with it, that's simply inherent to its halogen moieties.

DON'T EVER POUR DCM DOWN THE DRAIN
xylene is more of an eco-friendly chemical than dcm, trust me on this.

..interesting, how about chloroform or trichloroethylene?

they're less polar, but still have a dipole moment, because they're not planar. the true nonpolar halogenated-hydrocarbon is carbon-tetrachloride, but it is also the most toxic.

..i wonder if carbon-tetrachloride has the highest holding capacity of alks if it is the most NP?

probably.
but for all practical purposes and safety, chloroform is the best bet. it has the closest xlogp to dmt.

if you really want to play it safe, use xylene. I know it doesn't smell the greatest, but it will pull just about any alkaloid, and won't destroy the ecosystem if it ends up in groundwater.
you'd just need to let it slow evap outdoors

..thanks benzyme..yeah, chloroform is used in much of the classic literature..

Heptane is way too expensive to use for extraction, better off using it later on for purification/re-xtal so that smaller amounts can be used. There's been talk of using IPA with drytek or limtek, evaporating, then using heptane to purify. Otherwise use warm oil (veggie or limonene) or a stronger solvent and retrieve with fumaric acid: This will save you the trouble of smelly evaporation, but the fumarate would have to be converted to freebase.

Just to avoid the extra step of fumarate -> freebase conversion, I might just stick with heptane for extraction. Besides, a quick online search seemed to reveal negligible price differences between heptane and d-limonene.


If I were to extract with heptane, roughly how many pulls are necessary to extract most of the spice? And how much solvent should be used per pull?
