Example of isomer separation for Meth

[btcboss2022]

Hello,

After receive and see many questions about Meth resolution process I decided to show you an example with my own pics(not professional ones as you will see hahaha):

- 3.65L of "dirty" freebase(just separated and dried after hydrolysis process)
View attachment 20692

- 5.11L of water
View attachment 20693

- 2.55kg of L-tartaric acid(dextro-tartaric acid, d-tartaric acid)
View attachment 20694

- Mix the L-tartaric with the water until all dissolved
View attachment 20695

- Add the freebase to the mixture while vigorous stirring
View attachment 20696
View attachment 20697

- After around 2 min stirring the mixture is hot and becomes thick and later a solid mass
View attachment 20698

Now the process is practically finished just leave it at RT 24 hours and filter it with vacuum.
D-meth freebase will appears after after turning the liquid part alkaline(PH 13).

I hope this help you ;-)

btcboss2022I forgot to clarify that to avoid long discussions sorry hahaha

L-tartaric acid CAS 87-69-4

btcboss2022Hello, master, do you need to heat it during this period?

Hello, master, do you need to heat it during this period?

花谢花开I never did it, it's an exothermic process itself. Thanks.

btcboss2022 Do you recycle the L-Meth again the get a higher yield as in this diagram? :

FredDurstIs there any detailed description of this process? Is it the same for MDMA?

Mr Good CatThis diagram was the only bit of info I have found on this process. It is from a European law enforcement report explaining the different methods mostly found in EU. It didn't go into much detail.

Why would you need to separate isomers of MDMA?

FredDurstI love to resolve difficult questions. And it looks MDMA isomers are different from meth.

FredDurstNo

 

[hustlerkid]

You can apply the same principle in a different way by simple overreacting

Jordan BelfortCan you provide synthesis to convert L meth to D meth?

FredDurstPutting freebase back in a new reaction does the same

 

[btcboss2022]

Over reacting with ultrasound does exactly the same but depends on the reactants. I use a modified barbier type reaction without thf or any buffering solvent.

Goes from clear to cloudy to dark brown

Jordan BelfortHonestly I never used that and I dont know how it works I should study it but does exactly the same separating isomers or turning L-meth racemic ?
Because goes from clear to cloudy dont means anything specific could be for other reasons.

btcboss2022Very nice and simple explanation. Thanks

Good job great effort
I think it is better to add a nonpolar solvent and extract the nonpolar D base, since after alkalinizing the water, you collect the nonpolar base. Liquid/liquid extraction.

@btcboss2022
What are your ratios for 1kg base?

tartaric/base/water
700g/1000g/1400ml?

PLSYes

 

[Pulser]

Yes

btcboss2022Running a small batch.
70g tartaric (CAS 87-69-4)
140ml water
100g base.

Doesnt seem to form an l tartaric adduct.

PLSIf its water heat it till 100 Celcius.

PLSMix tartaric with water once dissolved add 100ml of freebase while stirring powerful some time if it don't works means that any of your reagents is not in good conditions anyway leave it 24 hours and check it later.

Interesting process nigger, and beautiful reactor. Keep it up!

btcboss2022Excuse me, liquid methamphetamine, do you not do distillation and split it directly? Will it affect the purity of the yield? For example, 10 grams after the same 15g distillation or 15 grams without distillation, which one will have a little more net weight? Can you answer it?

花谢花开No I dont distill it I make an acid base washing using 2 different solvents in the acid stage.
Possibly it could affects yield but in my experience is a very small amount and the final stuff has the same purity and the same cleaning level.
Personally the effort of steam distillation is not a profitable task.
Thanks.

btcboss2022Thank you for your timely answer. It's a pleasure to get a response. The picture looks really beautiful. It should be better to make a vacuum distillation. Try both vacuum distillation and non-distillation.

btcboss2022What kind of pickling do you use? How much ph is it? I washed ph5 last time, so I can't crystallize.

花谢花开I Dont know what pickling means sorry.
PH for washing must be 2 in acid stage and 12-13 in alkali stage.

btcboss2022Is the master still there? I have completed the splitting of the L-isomer in the water in your way. In the powder, does this powder still need to be added with water to continue to split? It seems that the split is incomplete. How do you deal with it? What should I do if I continue to split?

花谢花开You must turn it in FB again and later you decide.
If you need a complete guidance I have this service offered in the forum.

@btcboss2022 very nice shards my man! looks like you got it down pat, my Xtals get better as im always trying to improve tech, currently-clean clear FB > et20 hcl gas > filtered light vaccu to dry >reX boil ipa acs to solved-reduce till xtal starts in solution-cover vessel opening w/filter paper insulate w/ dish cloth to slow cooling>few hrs @ room temp > cap and place in freeze 1hr > filter light vaccu >vac oven 50*c med vaccu
any tips/recommendations @btcboss2022 ?? Ive been on the quest for growing large extra dense shards for quite some time now, I’d like to try crashing hcl product thats solved into liquid nitrogen sometime
