Nedaudz vienkāršāks metilamīna iegūšanas variants būtu nitrometāna CH3NO2 reducēšana līdz metilamīnam CH3NH2, izmantojot Al/Hg amalgamu.

CH3NO2 + H2 ---> CH3NH2+ H2O

🤔Man šķiet, ka tam ir kāds iemesls, jo lidmašīnas modeļa degvielas izmantošana metilamīna ražošanai in vitro ir izplatīts ceļš. vai nu tas ātri sadalās, vai... tas izklausās pēc enerģētiskas reakcijas.

Karsts, smags un smags! Man tagad sāp smadzenes. Es grasījos vienkārši noķert visu gāzi, kas izplūst no rxn, kādā HCl un pārējo izmest. Vai bez kavēšanās izmantot insitu.

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

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 :)
