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

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

This 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?

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

Excuse 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?

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.

Let me ask you the last question. What kind of pickling do you use? Before splitting? Do you mean adding tartaric acid to split after pickling to ph2? Acid and acid react crystallization?

You are mixing all data 🤦‍♂️
I use water but you can use methanol

Is 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?

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.
Thanks

@btcboss2022 a question, when you crystallize your d-meth in acetone, didn't you notice the powder you get is much much more fine than those from racemic?

I don't remember the last time that I crystallized racemic one sorry, possibly I did once long time ago I always crystallized D-meth and L-meth too sometimes.

Which L-tartaric acid (d-tartaric acid, d-tartaric acid) is used? Or use D? Or both?

Why many people ask things that are detailed in the post?Is easier ask them than read them?
If you are interested on it dont be lazy to read all post carefully.
Is nothing personal is a general reflexion sorry and thanks.

Hello sir, does the final filtered solution need to be adjusted to PH-13 by adding sodium hydroxide solution to obtain methyl free base?

Thank you very much for your answer. After obtaining the methyl free base, is additional drying required before crystallization?

Yes mainly to know the exact amount of FB to calculate the ratios of crystallization.

Sorry sir, last question, what do you use to dry the methyl free base here, tartaric acid/700g. Base/1000g. Water/1400ml. How much dry matter should I add?

Dear Mr.
Use L tartaric acid to separate the free base according to your method.
I got a chewing gum-like substance while stirring, and once I stopped stirring everything turned into a very hard white solid. A whole piece.
Is this correct?

sorry sir.
I'm a beginner. I followed your lead on the forum and synthesized.
From 5449~p2p I use the phosphoric acid method you shared. It worked the first time. Got a nice looking orange p2p.
From p2p ~ methamphetamine free base I used the sodium borohydride synthesis method you shared. It failed 2 times before. Later I got a light yellow oil. I don't know if he was methamphetamine freebase.
I followed exactly the method you shared.
Yesterday I used this oil. Follow the L tartaric acid separation you shared.

More than ten hours have passed now. It's very hard. Like ice cream in the freezer. There is no liquid present.

I'm very confused and worried right now.

Will it turn liquid after 24 hours?

The yield of free base from p2p~ was very low, 60 grams of oil was obtained from 100 grams of p2p. I don't know if it's because p2p is impure or why.
I don't have any basic knowledge of chemistry. It has been more than 2 months since I learned synthesis.
So far nothing has been found.
I'm so confused

It won't turn liquid the liquid is mixed with the hard solid you must crush it to vacuum filtration and get the liquid.
About freebase yield from p2p is ok if not steam distilled p2p used.

Dear Mr.

I used L tartaric acid to separate the free base. Vacuum gives liquid. Alkaline PH-13. Free base is obtained.

Stir the free base. Join HCI. PH value -2. I wanted to adjust the pH to -3. But the pH suddenly dropped. I'm careful to add very little HCI. The pH value has always been around 7 in the beginning. Then suddenly it drops to -2.

Heat to 130°. Pour into a container with 10 volumes of chilled isopropyl alcohol. A lot of powder immediately appeared in the container. Shouldn't we get crystals?

What did I do wrong?

Sir, please help me.
