I had this epiphany while freezing stuff with a can of air today.
I noticed that walgreens brand air duster is [almost] pure 1,1-difluoroethane, which should be substantially polar.

so here is the idea:

1. you get a pvc rig a-la supercritical butane extraction for pot, and load it up with powdered mimosa.

2. put enough sodium hydroxide CRYSTALS on top of the bark

3. run a can of difluoroethane through the pipe
I am assuming [hoping] that because of the polarity, it will dissolve the sodium hydroxide.
It should be noted here that at this point, there should be no holes drilled in the bottom of the pipe. The goal here is to dissolve the sodium hydroxide in the DFE, and as the DFE boil away in the pipe, it will be evenly dispersed among the bark, hopefully freebasing all the DMT.

4. drill the holes to make the traditional supercritical extractor

5. run a can of butane as a non-polar solvent through the apparatus

what do you guys think?

i know that the results are contingent upon the solubility, but I figured its worth a shot.
even if the second dissolution doesn't work, it would be nice to have an easy source of dry, freebased bark
 
IF that doesn't perform, how about first dampening the bark, then running NH3 gas through it, freebasing it in situ sans need for lye, then following up with the butane or other similar suitable solvent.
 
the problem I see with that is that the butane may or may not sink below the water, and may just float on top.
that is why my goal is to keep it dry.

what is wrong with lye?
it seems easier and cheaper

In the US the odor of ammonia will get your door kicked in quicker than just about anything.
 
Fryingsquirrel, due to the prevalence of the birch-benkeser reduction in making meth, right?

Easily scrubbed fumes though due to its basicity, just lead it through HCl, or whatever acid takes your fancy to yield the corresponding ammonium salt (nonvolatile)

I am not, bear in mind, a resident of the US, never been there, although I do intend to visit some day.
 
yes, birch meth. While the odor control you suggest should work, one little leak could spell disaster. There are literally announcements on TV here to call the police if you smell ammonia/ether/anyfuckingthing.
 
Damn, its worse than I even imagined over there then.

I wouldn't like having to live in a climate like that, wouldn't like to have to strap pipe bombs behind the doors just to do some household cleaning, clean off nail varnish or strip some paint, sheesh.

Those pricks at the DEA really do have some shit to answer for.
 
To be fair things are sorta out of control. A method called the "shake and bake", basically a birch in a bottle, has taken off like wild fire in the last couple years. I personally several people who've been badly burned attempting it.
 
Yeah I read about that, the article mentioned the cook having to 'burp' the bottle every so often or it blew up.

Carrying around a pop bottle full of anhydrous ammonia and lithium sounds frickin' scary to me, I used to make loud bangs with bottles full of Al/NaOH as a kid, and those were a bit eye-watering to be close to, but anhydrous NH3? damn, no thanks.
 
All in the same bottle? owch.

And to think, they could have the same result (albeit racemic) from any of the numerous routes to P2P.
 
1,1-Difluoroethane is not a polar compound. It will not dissolve NaOH. Its dielectric constant is 4.67, which is almost the same as diethyl ether. Compare this with water, with a dielectric constant of 80.
 
Also, butane wouldn't be a very efficient solvent for DMT.

All the light alkanes are poor solvents for DMT. The freeze-precipitation tek is based on DMT:s poor solubility in light naphta or heptane, DMT is somewhat soluble in warm naphta/heptane so it can be used to pull it, but when you cool it down it falls out of solution.

The solubility will just go down when the number of carbons goes down, so I'd expect DMT to have a very poor solubility in cold butane.
 
Bah, and I thought I had bad habits for adjusting my goggles to scratch my nose, or forgoing the use of a mask and using the great ourdoors as a hood, when working with things that bear no serious toxicity beyond irritant properties etc.

Whaddya know, I did get a lump of Na metal up the nose once for that nose scratch, but then again, they wouldn't have protected me anyway as it happened.

No joke, it went up there and burnt a crater when I was playing around with molten NaOH electrolysis as a kid, hurt like hell, because I got a bit sloppy and stopped paying attention.

But that just shows what tweakers will sink to, bloody scary really, I sure as hell wouldn't like to be around one of those shake'n'bake bottles that blew up, thats going to end up with a hellish atmosphere for breathing in no time flat, and if your close, melt your face off into the bargain...nice.

Although calling it shake and bake....bah thats piracy, a guy from the hive came up with that term for his nifty cyanate route to 4-MAR.

Fucking tweakers, grr, they ruin the fun for the rest of us sane, decent human beings who actually appreciate chemistry and biochem for its own sake.

dielectric constant isnt a measure of polarity, the dipole moment is

i'm still searching for it.

but knowing how electronegative fluorine is, especially compared to carbon, and the fact that both fluorines are on the same carbon, there is bound to be a significant dipole moment


edit: The dipole moment of 1,1 difluoroethane is 3.69 D, compared to 1.85 for water
its definitely polar

thats what I was afraid of,

but if the basification works, youd be left with a dry, freebase.
this is useful because you could soak it in heptane/naptha and use filterpaper to separate the pulp.
