Syntéza metylamínhydrochloridu. Veľký rozsah.

[handle]

O niečo jednoduchšou možnosťou výroby metylamínu by bola redukcia nitrometánu CH3NO2 na metylamín CH3NH2 prostredníctvom amalgámu Al/Hg.

CH3NO2 + H2 ---> CH3NH2+ H2O

Mám pocit, že je na to dôvod, pretože použitie paliva pre modely lietadiel na výrobu metylamínu in vitro je bežná cesta. buď sa rýchlo rozloží, alebo... znie to ako energetická reakcia

Horúce, ťažké a ťažké! Teraz ma bolí mozog. Chcel som len zachytiť všetok plyn, ktorý uniká z rxn, do nejakej HCl a zvyšok vyhodiť. Alebo bezodkladne použiť insitu.

Tu je dôvod, prečo sa redukuje na alkohol ( nadmerne redukuje, to je to, čo Rhodium hovorí " prevládajúca reakcia....." https://chemistry.mdma.ch/hiveboard/chemistrydiscourse/000460257.html

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

Tomorrow I will do an experiment.
9.34 mol **500 grams of ammonium chloride (NH₄Cl)
formaldehyde 37% (CH₂O) 12.7 mol approx. 1030 grams
Dcm and methanol

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

The product of tonight's synthesis is methylamine HCl.
Tomorrow I'll make a different synthesis, 750 +1500 gr
.

 

[NovicechemistEU]

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

 

[NovicechemistEU]

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?
