over the past few weeks ive read through the entire forum, as well as other forums,regarding this topic, but was unable to find a consensus on how to best approach this issue.

on a rather poor extraction (69rons tek) on my part(eyeballing amounts vs using a scale), i have 300g (powder) worth of goodies that evapped into a dark brown oily and sticky goo (approx volume = the size of a 1.25 cherries)

1. wash with mek (have not been able to find), so out of the question.

2. rebasify and resalt
-using 69 rons tek, but with 1/2 or 1/3 quantity of lime, vinegar and limonone needed for the original extraction? or substituting lime with lye and salting with hcl?

3. add dilute hcl to the goo, and wash with anhydrous acetone.

#2 and #3 being the only options, what is the best way to extract the mescaline out of the goo? i would like to hear of your thoughts/experiences. quantities/amounts for the above would be helpful. and in trying to get the goo to a purer salt, should i expect to lose some mesc in the process?

comments much appreciated!

In my experience, if you have something dark brown, there's no amount of wash thats gonna really clean it up, the best would be re-a/b ing.

You can either redissolve it in a small amount of warm water (no need for acid, if its in salt form it will dissolve very well), base with lye and pull with limo and salting, or do it by dry-mixing with lime and adding enough water to make paste, then pulling with limo and salting.

And yeah you wil definitely lose some significant weight in the process, but most of it will be impurity. If you add enough base, make very thorough pulling and salting (mixing very well, pulling/salting at least 3x), the alkaloid loss should be minimal, most loss will be impurity.

I remember once 10g black goo mescaline became 3g light orange crystal mescaline after re-a/b. Dont know how thorough I was, maybe youll do better, but just giving you a number so you have some idea.

Good luck, let us know how it goes!

I did the conversion to HCl once by adding an amount undilutted 10% HCl till it was dissolved. Afterwards I cleaned it with acetone and was also left with about 30% of off white crystals. So that corresponds with the rebasification and pulling with HCl. I would say if you really know how much HCl (pH is crucial) to add when you do a rebase so you don't have to clean it up afterwards go that route. Otherwise stay with the conversion and cleaning the acetate as it will take you less time and saves you some limo.

I recently had off white acetate without MEK cleaning. No waxy shavings but free flowing powder which crushed out the evap dish. 69Ron tek suggests 5% vinegar. This is way to acidic and will always result in the Goo. I dilluted the 5% vinegar till it reached pH 6. This was about 1 part 5% vinegar to 9 parts water.
You can check a post The Goo factor from Oneistheall. It's all about getting rid of the goo with acetate.

Also it's a myth that heating the acetate water will caramelize the product end give you goo. I evaported it off by boiling and afterwards drying the last bit in the oven at 100C. Not a trace of orange smudge was present.

great, thanks for the replies. will update
