Pozdravljeni,

po številnih preskusih z uporabo metilamin HCL na podlagi te metode bom z vami delil najboljši način, ki sem ga našel za pridobivanje metamfetaminske proste baze v velikem obsegu:

  • 966 gr P2P
  • 14 litrov metanola
  • 1183 gr metilamin HCL
  • 638 gr NaOH
  • 452 gr Brezvodni natrijev sulfat
  • 105 gr NaBH4
  • 35 l destilirane vode
  • 7 litrov DCM

- Reaktor napolnite s 14 l metanola
- Med mešanjem raztopimo metilamin HCL
- Temperaturo reaktorja nastavite na 0C (ne na temperaturo zmesi) in dodajte NaOH, temperatura se bo povečala
- Ko se temperatura vrne na 20 C, dodajte P2P, temperatura se bo povečala, mešajte od 45 min do 1 ure
- Dodajte 252 g brezvodnega natrijevega sulfata
- Ko temperatura zmesi doseže 8C, začnite po delih dodajati NaBH4, ki ne sme preseči 20C
- Ko je dodan ves NaBH4, pustite, da se mešanica meša pri temperaturi 20C približno 2 uri, dokler ne preneha mehurčkati
- Dodajte vodo in nadaljujte z mešanjem 5 minut
- Dodajte DCM in mešajte 10 min
- Prenehajte mešati in pustite, da se plasti ločijo
- Spodnjo plast obdržite, zgornjo pa zavrzite (ni koristno ekstrahirati te vodne faze).
- V ohranjeno plast dodajte 200 g brezvodnega natrijevega sulfata in jo premešajte
- filtrirajte v Buchnerjevem lijaku
- Izparite DCM
- Dobimo čisto in smrdljivo metamfetaminsko bazo

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.
