@gpatton veuillez dire à ce noob(moi) quel rôle jouent le NAOH et le bicarbonate de sodium dans cette synthèse. J'apprécierais une réponse.

117,6 % du montant 2-b-4-mp. Ecrivez-moi le calcul. (Astuce : c'est l'élément le plus lourd divisé par l'élément le plus léger.

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.
