Dmt Fumarate is disolved in the smallest amount of water and run thru a filter into a collection vessel.

a: (Quick Method) Copius amounts of acetone are added - All the pure DMT Fumarate falls out - Then into the freezer for the rest.

alternitavely

b: (For Xtals) An equal portion of acetone is added, ever hour for 4 hours - Then the vessel goes in the freezer.

Playing around with this i noticed one can get the fumarates to fall out at varous speeds, lower acetone ratio requires cooler temps.

Acetone Bombing (or any pairing) is the way of the future so far iv tried it on many salts.
Works Perfectly on methylone, mescaline, dmt fumarate, etc...

Il post some pix soon.

Pulls up a seat...

Phlux-, is it possible that you can either explain the mechanism here or perhaps link to somewhere where I could learn about what happens when you *bomb* the solution? It sounds interesting but I'd like to understand it before I blindly try something as vague as *adding copious amounts of acetone*
Why do the pure fumarates fall out?

Im no chemist, but from what I understand, it has to do polarity and consequently solubility. As acetone is added to water, its as if its not anymore water and acetone but a "new" solvent.. So adding acetone changes the polarity of this dual-solvent, and dmt fumarate, which is soluble in water but not acetone, will precipitate once it reaches a polarity closer to acetone. I guess phlux says "copious amount" because one needs excess acetone otherwise there will be still too much water keeping the fumarates dissolved.

Regarding how much acetone exactly, I was talking to phlux and he mentioned he was using a normal drinking glass as a container where the dmt fumarate was, and added very hot water dropwise till all the dmt fumarate dissolved (he was doing with 1g fumarates). Not much hot water is needed for that. Then (correct me if im wrong phlux) he added acetone till the glass was nearly full, and this went into the freezer.

thanks so much endlessness. Hope to learn more about this process. Sounds like it could be worthwhile.
And I apologize if my tone in the post above made it sound like criticism. I just find it hard to apply techniques that I don't have the vaguest idea of how the function, so I wanted to know...

yep end - dead right - but the disolved solids should be run thru a filter first if neccicary - and alternatively u can slowly drop the water into the same amount of acetone - it seems to make a difference in speed of precip.

Assuming you start with a clean salt and it fully dissolves in the water what would running it through a filter do?

if your salt is clean you wouldnt run it thru a filter - quoting me "yep end - dead right - but the disolved solids should be run thru a filter first if neccicary"

This is cool, and would probably work in the exact same way using IPA, but then again if you're doing a fumarate salt you can always dissolve in hot IPA and it will crash out as it cools.

It's funny, but isn't this the exact opposite of the tek you posted here? In that tek you suggest filtering the precips out and evapping the water/acetone mix to get the actives... Here you suggest collecting the precips as the active component. The way you describe it here makes much more sense than the other posted tek, because if you add acetone, the precips are going to be the actives, and the water/acetone mix will be mostly non-active impurities. Am I wrong about this?

just tried this but it didn't work. I assume my ratios were off? I had about 5-10ml of water and added maybe 300-400ml of acetone but nothing precipitated. put it in the freezer for a few hours, but nothing precipitated. There's about 400mg of goodies in there. I guess it's time for an evap...

anyone any ideas?

Not sure Enoon, but maybe you used too much water. I think you could dissolve a whole lot more thatn 400mg in 10ml.

Best evap.....see what's shakin

(1) Find out what volume/weight/drops water you need to dissolve 1g of the (pure as possible) salt. Next time you can use this information to dissolve an amount of the salt in as little water as possible. So your solution will always be close to saturated. Use hot (tap)water and give the salt some time when you can see it starts to dissolve.

(2) Find out the weight/volume of your drops of water. Weigh 100 drops and repeat a couple of times to get a nice average that you can use to calculate how much volume/weight is 1 or 5 of your drops of water.

(3) Now take 1L of acetone. Make sure it is a big volume (like 1L) and make sure you know the volume. Perhaps weigh a known volume of your acetone to be sure of the density of your acetone. If you compare this with the density of pure acetone (see wiki or so) you should be able to calculate how much water is in your acetone. You need very pure acetone, about 99%. If you know the density of your acetone you can weigh a volume. Dunno if that is practical but still..

(Z) Dropwise add your fairly saturated salt solution to the known volume (1L) of acetone. At start the concentration of acetone will be near 99%, so the salt will probably crash out immediately. But as you add more drops you will add more water. At some point the drops wont give rise to precipitates anymore. This is the point where there is too much water in the acetone. The salt remains dissolved.

Now you have all the information you need to figure out roughly at what % of your acetone your pap salt precipitates, or stays in solution.
