Un'opzione un po' più semplice per produrre metilammina sarebbe quella di ridurre il nitrometano CH3NO2 a metilammina CH3NH2 tramite amalgama di Al/Hg.

CH3NO2 + H2 ---> CH3NH2+ H2O

🤔Mi sembra che ci sia un motivo, perché l'uso di carburante per aeromodelli per produrre metilammina in vitro è un percorso comune... o si degrada rapidamente o... sembra una reazione energica

Caldo, pesante e duro! Ora mi fa male il cervello. Stavo per catturare tutto il gas che fuoriesce dall'impianto in un po' di HCl e scaricare il resto. Oppure usare l'insitu senza indugio.

Can u wash the methylamine with ethanol instead of chloroform? I have so many chemicals this is getting to be a small chem store.

I made the synthesis with a last minute decision in 3 lt capacity. The yield was good, I got 270 grams.
Ammonium chloride (NH₄Cl) 749 Gr
formaldehit %37 (CH₂O) 1546 Gr

My latest synthesis is methylamine HCl. It looks better this time, the next one will look better :)
I can't thank the forum enough.
The next synthesis is coming soon :)
1000+2000 Gr

Hi Bb team, I'm going to synthesize methylamine this weekend I'll make a slightly bigger batch. Ammonium chloride (NH₄Cl) 1250 g
formaldehyde 37% (CH₂O) 2500 g (with 15% methanol)
I'll write the results :)

Have you done a confirmatory test that its in fact methylammonium chloride and not ammonium chloride?
