Methamphetamine synthesis from P2P by NaBH4 reduction. Medium-Scale.

[malayboy]

Hello,

After many tests using Methylamine HCL based on this method I will share the best way that I found to obtain Methamphetamine freebase in big scale:

• 966 gr P2P​
• 14 liters Methanol
• 1183 gr Methylamine HCL​
• 638gr NaOH​
• 452 gr Anhydrous Sodium Sulfate​
• 105 gr NaBH4​
• 35 L distilled water​
• 7 Liters DCM​

- Fill the reactor with the 14 L of Methanol
- With stirring dissolve the Methylamine HCL
- Put the reactor temp at 0C(not the mixture temp) and add the NaOH, the temp will increase
- Once the temp come back to 20C add the P2P, the temp will increase stir it during 45min-1 hour
- Add 252gr of anhydrous sodium sulfate
- When the mixture temp arrives to 8C start adding portionwise the NaBH4 not exceeding the 20C
- Once all the NaBH4 has been added let it mixing under 20C during aprox 2 hours until the mixture stops bubbling
- Add the water and continue mixing during 5 min
- Add the DCM and mix it during 10 min
- Stop stirring and let layers get separated
- Keep the bottom layer and discard the upper one( not profitable to extract this aqueous phase)
- Add 200gr of anhydrous sodium sulfate to the saved layer and mix it
- Filter it in Buchner Funnel
- Evaporate the DCM
- Clean and smelly Methamphetamine freebase obtained

congratulations

malayboyPurity of this method?
What means DCM

 

[btcboss2022]

What about product yield?

G.PattonFrom 966gr clean P2P I got 950gr of Meth oil
From 966gr of "dirty" P2P I got 800gr of Meth oil.

MayaDCM is Dicloromethane

 

[G.Patton]

From 966gr clean P2P I got 950gr of Meth oil

btcboss202288.4% good yield

Here is the final ICE meth from the oil:

btcboss2022Did you separate D&L before crystal?

btcboss2022Hi sir. You follow this recipe? Can you teach me?

btcboss2022But it will melt

 

[Maya]

DCM is Dicloromethane

btcboss2022What alternative of this

 

[btcboss2022]

What alternative of this

MayaEther, toluene....

Very nice crystal cake
When you have final dry weight in grams please update with it, I have interest in seeing how much dry you got from 950ml of meth oil

ChingShihWell all ICE together around 800gr with all recovery stages done. I say this because I separate D and L and I must recrystallize the oil rest of each crystallization adding the dried rest powder of the acetone wash...hard job hahah

After using 950ml of pure meth oil, you get 800gr racemic meth is this correct?
When separating D and L isomer, how much D isomer do you get out of it?

ChingShih800gr with D and L weight together I don't get racemic one I separate isomers first directly from the oil.

800gr with D and L weight together I don't get racemic one I separate isomers first directly from the oil.

btcboss2022
Is this also possible? I hear for this for first time - separating isomers directly from the oil
Can you explain what is the process please? How to separate D from L in the oil?

ChingShihOf course is possible I told you I did it, unfortunately I can't share that info my partners don't allow me that because we invest some money to obtain that method. Thanks.

ChingShihIt's simple procedure with d-trataric acid. Look at this method, same with meth.

 

[situ1984]

It's simple procedure with d-trataric acid. Look at this method, same with meth.

G.PattonShould I use d-tartaric acid directly? Can I get D by cleaning the oil produced by btcboss2022 method?

 

[G.Patton]

situ1984Can you be more specific? What method do you refer to? What do you mean directly? This method (which I linked) is direct.

G.PattonIs not exactly the same is more complex but this method will work too.
