Labdien,

Pēc daudziem izmēģinājumiem, izmantojot metilamīna HCL, pamatojoties uz šo metodi, es dalīšos ar labāko veidu, ko es atradu, lai iegūtu metamfetamīna frībāzi lielā apjomā:

  • 966 gr P2P
  • 14 litri metanola
  • 1183 gr metilamīna HCL
  • 638 gr NaOH
  • 452 gr Bezūdens nātrija sulfāts
  • 105 gr NaBH4
  • 35 l destilēta ūdens
  • 7 litri DCM

- Piepildiet reaktoru ar 14 l metanola.
- Maisot izšķīdina metilamīnu HCL
- Uzstādiet reaktora temperatūru 0C (nevis maisījuma temperatūru) un pievienojiet NaOH, temperatūra paaugstināsies.
- Kad temperatūra atkal sasniegs 20C, pievieno P2P, temperatūra paaugstināsies, maisot 45 min-1 stundu.
- Pievieno 252 g bezūdens nātrija sulfāta.
- Kad maisījuma temperatūra sasniegs 8C, sākt pa daļām pievienot NaBH4, nepārsniedzot 20C temperatūru.
- Kad viss NaBH4 ir pievienots, ļauj maisījumam maisīties 20C temperatūrā aptuveni 2 stundas, līdz maisījums pārstāj burbuļot.
- Pievieno ūdeni un turpina maisīt 5 min.
- Pievieno DCM un maisījumu maisa 10 min.
- Pārtrauc maisīšanu un ļauj slāņiem atdalīties.
- Saglabā apakšējo slāni un izmet augšējo (nav izdevīgi ekstrahēt šo ūdens fāzi).
- Saglabātajam slānim pievieno 200 g bezūdens nātrija sulfāta un samaisa.
- Filtrējiet Buknera piltuvē
- Iztvaicējiet DCM
- Iegūta tīra un smaržīga metamfetamīna brīvā bāze

Is the 35 litres of water added to ensure seperation of the dcm and water cos of the methanol present to stop it all mixing?
and are you using a 100 litre HDPE paint bucket as the reaction vessel?

Is 15g of NaBH4 enough as the reducing agent for 138g of P2P? Or should I add a small amount of reducing agent to avoid some side reactions?

Hello, yes it's not enough. You have to add at least equimolar amount 38.91g of NaBH4. It's even worth to add a little more, ~1.1 eqviv 42.8g.

Idol, there must be a special reason why you choose to use less reducing agent! For example, to avoid certain side reactions or to favor certain steps? Please Master, please enlighten me on the mystery behind this.
