Syntese af mephedron (4-MMC) [2B4M, ethylacetat, methylamin HCl].

Det ville være fantastisk at have en video af denne syntese

Der er en i videoafsnittet. Præcis dette

@gpatton, fortæl venligst denne noob (mig), hvilken rolle NAOH og natriumbicarbonat spiller i denne syntese. Værdsætter et svar.tak

117,6 % af 2-b-4-mp-beløbet. Skriv udregningen til mig. ( tip: det er det tungere grundstof divideret med det lettere

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.
