The FASA Method: A Summary - DMT Fumarate and Beyond

Migrated topic.
has any other SWIM heard the sound of their dmt fumarate tumbling together inside their little jar/container after they are all dry?? haha it sounds like a salt shaker;)
 
Does the acetone really have to be anhydrous? Does 5ml water per litre acetone make that much difference (if using 99.5% acetone)? Also read somewhere that you could use NaOH to make anhydrous Acetone. What about the water in 99% fumaric?


Edit:

I really should try reading other posts before asking silly questions but then its late and it can get confusing with all these different teks and chemicals etc - BAH I'm going to bed.

That's what SWIM's FOAF paid for 45g. It is very pricey, but he does not regret it at all. After all, 45g are enough for salting 140g of spice, and he does not even aspire to smoke as much in his lifetime.

One may even be able to buy cheaper,


As far a malic acid is concerned, it can indeed be found very easily, e.g. in breweries. But I have no clue on how it would perform. If someone is planning to use it he/she should firs establish that

1) malic acid is soluble in acetone

2) dmt malate is totally insoluble in acetone

these are the key virtues upon which the FASA is based

Would be really nice to hear back from success with malic acid.

No. Malic acid won’t work. SWIM already tried it. It produces a sticky goo like all the other common acids. Malic acid is far more water soluble than fumaric acid. Water solubility for malic acid is 36.35 g/100 ml. You need an acid that is practically insoluble in water or else you end up with a goo. I think the only other option is picric acid which is explosive!
 
Great thread, and great research. I've been away from the site for a while and the advances noted here have really surprised me.

I'm definitely going to give this a try once I can get the supplies together, on that point does anyone know of a good source for Fumaric acid in the UK, I've checked a few healthfood/vitamine stores but none of them have it - no surprise there, they're generaly understocked compared to the U.S.A.
 
Thank you. SWIM has placed the order. As what another poster said, Google wasn't very helpful. All those Chinese sites trying to sell 25kg of the stuff.

Does one need to purify Xylene using 50/50 water first to remove sediments, before doing FASA?

Also, can one use Xylene instead of Acetone?
 
For the SA part of the FASA. Mixing Fumaric acid with Xylene since Xylene would be used for the pull anyway.

Maybe I should have read better. Now that I think about it, there's a reason Acetone goes with Fumaric acid, separate from the Xylene pull.
 
I suppose it's possible, I don't know that anyone has tried it. If fumaric acid is quite soluble in xylene it seems like it would work. Acetone is just such a ubliquitously available solvent (and is known to work and dissolve fumaric acid well) that it seems like the convenient choice.
 
How much citric acid saturated acetone would it take to pull a gram of spice?

Is the citrate salt more or less soluble in acetone than the freebase is in naphtha?
 
SWIMS FOAF is getting cheap Fumaric acid (cheaper than £28 for 45g anyway) and plans to sell on ebay etc for around £3 for 50g - that is if it ever gets here. FOAF got an email saying it would be delivered this week.
 
k- so should one bother with a wash of their STB product using this method? Will bits of water/basified muck from a sloppy separation cause problems with this technique?

Also, aprox how much fumaric acid per expected gram of spice should one be using, swim understands an excess is called for- just wants a ballpark figure
 
Ok, capsules that are 500mg each aren't that precise. And a scale I'm waiting on only measures in 10mg amounts. I read we can use more fumaric acid when mixing with Acetone, or are the ratios really critical?

Yes, they will. It may make a mess actually. On the otherhand, separating layers is pretty much an elementary skill to learn, it would be generally assumed that one does not have a sloppy separation to begin with!

SWIM's FOAF does not want to know how things could turn out in such a case. If water is present in the xylene/toluene, then the dmt fumarate will be dissolved into it. And since the water will most likely be basified with NaOH, some of the dmt fumarate will be freebased and hide inside the xylene/toluene. Any way one tries to see it, bad separation just asks for unnecessary trouble. Just get only the solvent out, it's easier!

Re to the first question, the STB dmt-fumarate product can be washed with clean acetone, just to remove any residual lipid impurities, and any xylene/toluene.
 
no...dmt and fumaric acid can only group together in one way...2 molecules of dmt for 1 molecule of fumacic acid..

just mix the fumaric acid in with acetone..and once most of it gets absorbed..just start dropping some of the FASA in the dmt acetone..and then wammy! out comes dmt fumarate
