Uma opção um pouco mais simples para produzir metilamina seria reduzir o nitrometano CH3NO2 a metilamina CH3NH2 através de amálgama de Al/Hg.

CH3NO2 + H2 ---> CH3NH2+ H2O

🤔Parece-me que há uma razão, porque utilizar combustível de aviões modelo para produzir metilamina in vitro é uma via comum... ou se degrada rapidamente ou... parece uma reação energética

Quente, pesado e duro! Agora dói-me o cérebro. Eu ia simplesmente apanhar todo o gás que escapasse do rxn num pouco de HCl e deitar fora o resto. Ou usar o insitu sem demora.

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?
