Im reading in to the FASI teks and I dont understand 2 things. Maybe I am asking a question that is already answered, but I cannot find the answers.

Assuming: 100ml limonene has 100mg dmt in it, how much FASI does one has to add to make fumerate crystals to grow / precipitate? What is the ratio for solvent and FASI? Does it change if 100ml limonene would have 500mg dmt in it?

If you would add 100ml fasi to the 100ml limonene, would that be too much? Or would the result just be more fumaric acid than dmt in the fumerate, and therefor a yield that is off?
A wash could get rid of the excess fumaric acid, I assume?


EDIT:

So maybe its all about the interpretation of the sentence "One cannot put too much FASA". Does it mean --> Put as much in it as you want, it will never be enough.

OR does it mean: Do not put too much, because it wont work.

It means you can keep adding and it will never really be `too much`, it`s not a problem.

The excess fumaric acid will generally just stay in solution. So for example, once all the alkaloids are precipitated, if you try to add more FASI/FASA, it will just mix in and stay in solution, but if there are still more alkaloids to precipitate, you will see the solution gets cloudier immediately.

The amount of FASI/FASA necessary will be related to the amount of alkaloids in solution, so the more alkaloids there are, the more you will need to add. But as mentioned above, you don`t have to worry about adding too much. Generally, just to give you an idea, for 600ml limonene that extracted 200g mimosa, you could prepare 200ml FASI. Just add it slowly and when you see it doesnt get any cloudier you can stop adding. And after a couple of days you can try adding a bit more and see if it ges cloudy again, if so add more, if not then just wait a few more days so that it finishes precipitating.



The best when doing FASI/FASA is to add it very slowly to the limonene. The slower you add, the nicer crystals will grow.. Ideally one would make a contraption so that there is a drop falling every few seconds, and just forget about it and leave it for a few days.

Once again: Thank very much endlessness ... you cleared things up, I understand it now.

in addition to endlessness,

You need 309 mg of fumaric acid for every 1000 mg dmt.

Yeah ive read that too, so theoretically and if my math is correct:

309mg fumaric acid is needed for 1000mg dmt and given is, that 100ml 99.9%IPA can hold ~2,5gr fumaric acid.

For a extraction using 50gr of mimosa bark containing 1% dmt you would need 6.18ml of complete fumaric acid saturated IPA. And just to make sure you dont have bark that does contain 2% or 3% dmt (who knows), you should add ~18.5ml FASI (6.18* 3) to the X amount of limonene.

But with limonene you will always pull more then 1% full spectrum, so it would be logical to add 3 or 4 times the amount of FASI. Unless a somebody can tell if it matters how much limonene is used, because the alkaloid molecules have more "space" to move around. And therefor it would be preferable to use a larger amount of FASI.
