Metamfetamiini süntees P2P-st alumiiniumamalgaami abil

[Fenster]

Kas metanool võib asendada etanooli lahustina?

 

[Ranof]

Yes, it's even better.

 

[Ranof]

But the risk of toxic gases increases.

See kirjutis on täielik segadus. Selle järgimine sellisel kujul annab teile 10% yld. Või võib olla ka vähem.

1. Alumiiniumamalgaam tuleb eelnevalt ette valmistada, see on oluline samm
2. Lisage oma p2p, metüülamiin amalgaamile koos isopropanooliga.
3. Hoidke reaktsioonitemperatuur <30 kraadi
4. 40g p2p ja 40g alumiinium FOILiga saate 100% runaway .
5. Lisage NaOH/KOH enne filtreerimist Al/Hg muda, see muudab filtreerimisprotsessi lihtsamaks ja tapab allesjäänud Al
6. Ja nii edasi...

Ma tegin enne 200L trumlidel, 100L trumlid on ka hea, ja tegin ühe poti reaktsiooni.

350-400 grammi elavhõbedat 10L b (400 grammi on tõesti palju agressiivne), 15L metüülamiini 40% ja siis nagu 30L metanooli.
Fooliumiga ma ei ole kindel, mul oli lõpuks tehtud nagu 2/3 ämbritäis kriimustatud/kahjustatud fooliumiga (pallid puuduvad), nii et see oli see kaal.

Lõpuks oli liiga palju fooliumi.
Saagis; 12L PH 12 juures.

Tagasi metüülamiiniga, kõik teavad, et on paremaid alternatiive, kui töötan, nt Al/Hg-ga

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 D.]

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