Sinteza metilaminijevega hidroklorida. V velikem obsegu.

[handle]

Nekoliko preprostejša možnost za proizvodnjo metilamina bi bila redukcija nitrometana CH3NO2 v metilamin CH3NH2 s pomočjo amalgama Al/Hg.

CH3NO2 + H2 ---> CH3NH2+ H2O

Zdi se mi, da obstaja razlog, saj je uporaba goriva za model letala za izdelavo metilamina in vitro pogosta pot. ali se hitro razgradi ali ... sliši se kot energijska reakcija

Vroče, težko in trdo! Zdaj me bolijo možgani. Vse pline, ki uidejo iz rxn, sem nameraval samo ujeti v nekaj HCl, preostanek pa odvreči. Ali pa nemudoma uporabiti insitu.

Tukaj je razlog, da ga reducira na alkohol ( preveč ga reducira, to je tisto, kar pravi Rodium z " prevladujočo reakcijo....." 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?
