Merci beaucoup pour ces connaissances gratuites.
Cette solution de méthylamine peut-elle être transformée en 60 %, et peut-elle être utilisée pour la fabrication de produits chimiques ?

Merci de votre réponse.

Bonjour, quelle solution demandez-vous et quelle est la méthode d'hydrogénation ? Pouvez-vous être plus précis ?

Le chlorhydrate de méthylamine peut-il être transformé en une solution aqueuse à 60 % et cette solution peut-elle fonctionner dans l'alkylation réductrice via la méthode d'hydrogénation catalytique ?

Je veux dire utiliser de l'hydrogène gazeux à la place du papier aluminium.

Teacher, may I ask if after adding sodium hydroxide to the water and stirring until dissolved, it will no longer be transparent!

Teacher! May I ask if there is a diagram for the 40% synthesis method of methylamine water?

Teacher, may I ask if the second bottle of 600ml water is filled with methylamine gas? If the 600ml of water reaches 1kg, then it is considered complete, right?

If there is no reaction after adding methylamine hydrochloride to the sodium hydroxide solution, do we still need to add 869 grams?
