Sinteza metamfetamina iz P2P prek aluminijevega amalgama

[Fenster]

Ali lahko metanol nadomesti etanol kot topilo?

 

[Ranov]

Yes, it's even better.

 

[Ranov]

But the risk of toxic gases increases.

Ta zapis je popolna zmešnjava. Če ga boste upoštevali takšnega, kot je, boste dobili 10 % jela. Lahko pa tudi manj.

1. Aluminijev amalgam je treba pripraviti vnaprej, to je pomemben korak
2. Amalgamu dodajte p2p, metilamin in izopropanol.
3. Temperaturo reakcije vzdržujte na < 30 stopinj
4. S 40 g p2p in 40 g aluminijastega FOIL-a boste dobili 100-odstotni pobeg .
5. Pred filtriranjem blata Al/Hg dodajte NaOH/KOH, kar olajša postopek filtriranja in uniči preostali Al
6. In tako naprej...

Pred tem sem delal na 200-litrskih sodih, 100-litrski sodi so tudi v redu, in opravil reakcijo v enem loncu.

350-400 gramov živega srebra na 10L b (400 gramov je res veliko agresivnega), 15L metilamin 40% in nato kot 30L metanola.
Glede folije nisem prepričan, na koncu sem naredil približno 2/3 polnega vedra z opraskano/poškodovano folijo (brez kroglic), tako da je bila to ta teža.

Na koncu je bilo folije preveč.
Donos: 12 l pri PH 12.

Takrat z metilaminom, vsi vedo, da obstajajo boljše alternative za to pri delu, npr. z Al/Hg.

When you say the Al amalgam can be made in situ does that mean one doesn’t have to wash & decant the HgCl from the aluminum before introducing the p2p + methylamine mixture? The HgCl can be left in the flask while reduction happens and will be extracted out later during product purification?

I'm currently experimenting with al/hg and wanted to scale the synthesis. I asked myself the question of whether it is absolutely necessary to use a capacitor? I suspect it is needed to keep the methylamine and solvent (methanol) in reaction vessel. But would it be possible to compensate for methylamine loss with a new methylamine-methanol solution?

 

[Chemist Jun]

Perhaps an excess of methylamine was used, not much, just to compensate
Add an amount of water
Keep the temperature no more than 60 degrees and you will be fine

 

[Acab1312]

Thanks Perfect will try

 

[Chemdogkm]

shouldnt be much lost at good temp and condensor

 

[Acab1312]

My goal is to do p2p in about 10L per lap.

 

[Dephoj]

Hello,is it possible to replace methylamine with something other ?thanks

 

[William Dampier]

I have heard of success with nitromethane, but the yields are lower.

 

[Jordan Belfort]

I cannot say that the yields where lower with nitromethane, but do not underestimate the danger of nitromethane.
you need 600L nitromethane per L [MD]P2P.

Hello. I'm like a kid in a candy store. This forum is wonderful. Thank you for your work.
