No big deal.
Just defat the acidic solution before you do step 6.

Why did you use naphtha? I'm not sure how well naphtha works for mescaline but that tek calls for xylene. I prefer toluene personally.

Sounds like your mescaline is in the naphtha. I would salt it out and rework from there - de-fat, base it and salt it out again.




He doesn't have an acidic solution, he based it already!

Mesc not very soluble in naphtha

He going to have an acidic solution right before he does step 6 though won't he?

defatting is a pain compared to basic crystallization/recrystallization
and you will want to reX anyways, so it is a major waste of time and resources ime

ps, murple is/was a smart guy, but things have come aways in 10years.....
as an example, look at MHRB extraction advances in the last 2-5yrs

The best tek for cacti IMO is this one.
No defat just base, pull and salt.
You can get really clean white mesc easily with little to no post wash if you use toluene to pull and HCl to salt.

So I can assume you've done this?
Because the tek calls for acetic acid to pull:
"This vinegar will contain mescaline acetate. Evaporate your vinegar in a food dehydrator at 155 F to get waxy amber slightly impure mescaline acetate."
and that's what I've gotten every time using a drytek on cactus unless I precipitated with FASA, and even then the yield sucked.
I'll do a side by side with an A/B if you'll verify that this is the way to go.

Here is a post I made the first time I did this.
I did the "Pure white mescaline HCl" tech. Its the 2nd part of the wiki page I linked.
I have consistently gotten these results ever since. After salting I filter twice before evaporating. My yields are usually around 0.7%-0.8%

Nice!
Seems another try is in order.

I did. Salt the alks out of the NP and defat the acid solution before doing step 6.
Mysmelf said the same thing - and he's right, mescaline isn't very soluble in naptha, so the alks might still be in the basic solution.
