È possibile trasformare il cloridrato di metilammina in una soluzione acquosa al 60% e questa soluzione può funzionare nell'alchilazione riduttiva con il metodo dell'idrogenazione catalitica?

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 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?

Teacher, do you mean to heat the flask containing methylamine free base to boiling and let the water flow together to the second flask?
