Super bi bilo, če bi imeli na voljo videoposnetek te sinteze

Na voljo je eden, in sicer v razdelku z videoposnetki. Točno to

@gpatton Prosim, povejte temu noobu (meni), kakšno vlogo imata v tej sintezi NAOH in natrijev bikarbonat. Cenim odgovor. hvala.

As Hanna520 wrote in the another thread, it is better to prepare alc. methylamine for this synthesis. You will get fewer problems associated with the hydrolysis of ethyl acetate. You can use triethylamine, ethanol or methanol, or THF. Get a solution of gas and a precipitate of salts without water. It is easy to separate by decanting and you can start your synthesis more successfully. For small quantities this is usually not a problem, but if you want to synthesize several kg at a time it will be significantly different.
