Σύνθεση μεθαμφεταμίνης από P2P μέσω Al/Hg

[Pinkbay]

Sir, can I use 35% methylamine in methanol instead of methylamine in water?

 

[Speedfac]

yes , Methylamine in Methanol its 33%.

 

[Pinkbay]

thx a lot, sir.

You have mentioned about oxidation here,
it takes me almost 7-8 hours to filter the mixture,
Because when I use vacuum, vacuum filtration cannot happen because of the aluminum amalgam sludge,
That's why I first pick up the aluminium dust through a cloth, due to which a lot of the aluminium dust comes out with the liquid, then I filter the filtrate through filter paper, which takes a lot of time
Will taking too long for filtration lead to meth base oxidation,
I also smell a lot of methylamine gas during filtration,
what effect will this have, can the meth base get spoiled due to oxidation,
how much effect will this have, please share your opinion

Instead of being oxidized by oxygen, the methamphetamine free base forms the methamphetamine carbonate salt with carbon dioxide in the air.

I am making p2p by ethyl 2 chloropriponate method, and I have purchased methylamine solution 40%, after that I am doing the whole synthesis process step by step as shown in the video, only filtration is taking me a lot of time, but I am not able to understand whether I am getting methamphetamine free base or not, because after evaporating the dcm very little amount of oil is remaining, after introducing it again through hcl gas I am not getting the salt

 

[lalalander]

Why don't you just use NaBH4? Also you can get a yield around 85% of the glycidate you get with Ethyl-2-Chloropriponate by adding aqueous Oxone solution to a-Methyl Cinnamic Acid in acetone and NaHCO3.

Benzaldehyde + MEK = 3-methyl-4-phenyl-3-buten-2-one

3-methyl-4-phenyl-3-buten-2-one + NaClO = a-Methyl Cinnamic Acid

a-Methyl Cinnamic Acid + Oxone in NaHCO3 buffered Acetone = BMK Glycidic Acid

BMK Glycidic Acid + NaOH = BMK 5449

Sir! What was the synthesis temperature? Did you do it in ice bath?

 

[Arakava]

I made p2p by bromine and benzen. And made 40% aqueous methylamine.
Then synthesis it by Al/hg. After filtering the aluminium amalgam. I did a steam purification. And seperated fb from ethanol and water by dcm. Then evaporated the dcm.
What's left was a pale yellow oil.
How can I make sure it's free base racemic meth?
It smells like methylamine but not that strong. I mixed it with diethyl ether then introduced hcl gas to it. It didn't give me any salt. I evaporated the diethyl ether. Some salt appeared. But smoking it had no effect.

 

[GhostChemist]

You couldn't synthesize p2p by using only bromine and benzen

 

[Arakava]

First I synthesis bromoacetone. Then synthesised penylaceton by bromoacetone and benzene in the presence of alcl3 as catalyst

 

[GhostChemist]

"How can I make sure it's free base racemic meth?" use Simin`s test or standard test-strips

Hello master, this one is methylamine hcl or freebase? Thanks

 

[Playernumber1]

Thanks very much for the write up.
Iv been playing around with the different meth synths trying to get to grips with it.
Is there an al/hg version with that's more commercially compatible?
For me to process 100 liters of p2p I'm looking at over 4 and a half tonnes of liquids.
Any advice would be greatly appreciated and I would be happy to pay for working commercial script
Iv looked all over this amazing site without any luck.

 

[Arakava]

Are you going to supply the whole gallexy? lol

 

[GhostChemist]

For commercial use more applicable and scalable synthesis with NaBH4

[Playernumber1]

Thanks for the reply.
Yes that's the conclusion iv come to.

I was just on the rhodium site available on erowid, there are a number of references to large reactions, like 100g even 1000g. I have read here that not to do more than 40g. just wondering.

 

[Idontcarethatmuch]

The bigger the scale the worse is the problem with heat. The higher the heat the less you'll get of the theoretical yield. Roughly said...

If you want to do large scale do nabh4/cucl2

 

[should]

Sir, what role does CuCl2 play in NabH4?
