Sinteza metamfetamina iz P2P z redukcijo z NaBH4. Srednja stopnja.

[btcboss2022]

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

Excuse me! After dissolving methylamine hydrochloride in methanol, the next step is to add sodium hydroxide at an ice bath temperature of 0 degrees, right？

Am I missing something, can you not simply steam distill the meth freebase directly from the reaction mixture once complete?
Or is there just too much water to freebase ratio for that not to work?

 

[GhostChemist]

steam distillation can not be applied for this RM

While introducing hydrogen chloride gas from an HCl generator, I am encountering leakage and pipe ruptures. Could anyone recommend a suitable type of piping material or fittings for this application?

Hi. Borosilicate glassware and PTFE also good. Silicone hoses also suitable.

Thanks for your reply. Please tell me the name of exact equipment. (Tube or etc).

Teacher! Does setting the reactor temperature to 0 degrees mean adding sodium hydroxide after the ice bath temperature is set to 0 degrees?
