Swim cant seem to find tolulene and heptane but has found xylene- he would love to do a jungle pull but has read xylene takes forever to evap and stinks - how should swim go about using it in the best way ?

FASA...but would somebody explain to SWIM...do you still use acetone to make the solution if xylene is the solvent??

swim doesnt wanna go the fasa route - unless someone can point out benefits over the stb route -
should swim use xylene or go on an all out search from tolulene and heptane ?

There is no comparison between FASA and STB or A/B. FASA is the follow-up of these standard methods and is used in conjunction with them. It is by far the most reliable way to avoid xylene evaporation, avoid lipid contamination and get the purest alkaloids out of it.

SWIM's FOAF had written a tek explaining the whole thing and what to do afterwards, it can be found here under one of the postings.

concerning your question xylene is fine solvent to use. evaporate under heating in a well ventilated area. When most of it is gone dissovle the mixture in pure alcohol and then re-evaporate it to get rid of residual solvent.

Why evaporate in ventilated area? the smell of xylene is awesome!

Haha While you may like the smell all aromatic hydrocarbons like benzene toluene and xylene can sometimes can converted in the body to potentially toxic compounds that can potentially damage ones DNA and thus are slightly potentially carcinogenic. While the risk is low and SWIM does not worry about it, its still a possible hazard. Plus the flammability part.

so when doing the FASA with this..you mix the fumaric acid saturated ACETONE with the xylene?

Yes, dropwise, but too much FASA in the xylene is not a particular problem.

would any other than spice-fumarate come out? like if there WAS an excess of FASA would any of the fumaric acid settle after a few hours?

No. But Jorkest, refer to SWIM's FASA tek on Entropy's FASA Overview thread. SWIM's FOAF has attached a DOC document detailing the procedure and explaining the steps. It's not the best place for it to be at the moment but we'll sort it out.

Addition of FASA in xylene causes basically close to zero precipitation of fumaric acid. Even if 1000 molecules actually precipitate, when the alkaloids are washed 1-2 times with acetone the fumaric acid will go away, And even it 10 molecules of it remain, they will be left out when the spice-fumarates are turned to their freebases

well then SUCCESS!! SWIM has about 10mg+ of dmt fumarate and friends from maybe 2-3 grams of phalaris brachystachy that he has growing

he made a basic water solution with lye and let the wet grass sit in it for a few days...so that everything would break down really sweet...and then extracted with xylene..and added fumaric acid saturated acetone..and let it sit for a bit..and there was a nice white film over the jar...which hes been slowly pushing together...he just needs to test it now...

can you smoke dmt fumarate? because if he tried to freebase it..he would probably loose quite a bit of this small amount of material

edit: and heres another little question...when you go to freebase the fumaric dmt...wouldnt the acetone pick up the fumaric acid that just got pushed off by the base?

edit2: SWIM would say there is actually more than 10mg...closer to 30mg..he said he will weigh it in a second

it was actually 115mg of some nice crystally crystals...maybe it was more like 5 grams of phalaris brachy..it was wet when he did the extraction..but he never weighed anything...but it was just about 5 grams..it must have been..not sure of the wet weight..but according to the phalaris brachystachy info thats out there 3% might not be too off...there is a very nice size pile of this stuff...how exciting..

and SWIM didnt have to do any defatting at all..it was so easy

now just need to test it out

No, because with a calcium hydroxide paste one will have:

dmt fumarate + calcium hydroxide -> dmt freebase + calcium fumarate (+ unused calcium hydroxide)

both calcium fumarate and calcium hydroxide are totally insoluble in acetone!

With sodium hydroxide paste one will have:

dmt fumarate + sodium carbonate -> dmt freebase + sodium fumarate + CO2 (escapes in the atmosphere) + unused sodium carbonate.

Again , both sodium fumarate and sodium carbonate are insoluble in acetone!

Hope that helps!

ahh thank you...now i understand!!

The FASA is the best adjunct ever to STBs or A/Bs. SWIM's firmly convinced about that. Again, it's very nice to see people getting nice results with it!

if swim uses xylene in place of naptha on the stb like usual will it pull a mix of spice and jungle ?

should all the spice be pulled with naptha then use the xylene for jungle ?

can xylene be used for freeze precips ? - can jungle even be freeze precipped ?

Yes, xylene or toluene will pull more alkaloids. Not a problem, all are smokeable and all beautiful


Only if one wishes to separate them. But xylene pulls after the naphtha pulls will still pull plenty of dmt along with the other alkaloids. Which will need to be cleaned with naphtha...So SWIM's FOAF believes it is far better to begin with xylene pulls, then wash the dmt out of it using naphtha. But the latter will require evaporation of the xylene (pain in the ass) unless one goes FASA.


No, it cannot be used for freeze precipitation. Unlike naphtha, it is a really good solvent so it will not release the alkaloids it holds when its temperature drops.

okay one more kwestion - what temps should the xylene pulls be done at and also will it make my spice cleaner if i disolve it all in naptha and re freeze precip ? if so how hot should the naptha be caus iv read that spice vapes at low temps - 50 degreez centigrade ? last time swim tried the naptha didnt wanna disolve nicely.

Xylene pull should be strictly performed at 28.82 Celsius. This is very critical and I am very serious about that. This is re to the first question.

Re to the second, I presume you mean if you evaporate the xylene, then wash with warm naphtha. Then yes, 50 centigrade is fine but no more than that. Spice evaporates at ~60-70 centigrade. Note that naphtha is not the best solvent for spice. So, depending on the amount of it, the amount of naphtha used and the temperature of naphtha not all of it may get dissolved.

So, one can get the stuff from the evaporated xylene and wash it with a small amount of warm naphtha say 50ml, then freeze precip. Collect the precipitates next day then warm the naphtha and use it for the second wash. Do it a few times. It is reliable and not really time consuming.
