Hi..
SWIM was doing a normal Naphta-STB Extraction, and had some Leftover Sludge from an older Extract, which he started pulling with Xylene to Fasa it out after adding later pulls..
Then Then he got interrupted, and when going on, he felt somethings not right here..

He had First Xylene Pull from Slurry (ca. 30 ml), and freshly, long soaked orange colored Naphta..and put some of the Naphtapull (ca, 15 ml) by mistake and it inthe Xylene-Pull...??

He still has enough orange Naphta-pull here, for going on with his project, but what about the Xylene he already pulled??
Is there a way of cleaning both Solvents from each other again, or shall he just add next 2 Xylene Pulls and start Fasa it?? Would the n,n-DMT as well just pprecipitate forming to Fumarate, or would he need to do something with the Xylene Pull, first??
Please help someone please..

Just salt the xylene/naphtha out with FASA or FASI; this will precipitate the alkaloids. Then get rid of this xylene/naphtha solvent as I guess it won't be much useful.

There'll be a fair amount of just fumaric acid precipitated along with the alkaloids but this will pose no problem freebasing it any way you plan freebasing it.

This is the result from doing FASA it..
Nothing is precipating..



Shall i just add more FASA??
Whats the ratio of Xylene and FASA anyway?

But it's cloudy, so theres' definitely insoluble material suspended; you need to let it settle (=precipitates). It's not that sinking of huge chunks of alkaloids occurs instantly.
