¿Puede convertirse el clorhidrato de metilamina en una solución acuosa al 60% y puede funcionar esta solución en la alquilación reductora mediante el método de hidrogenación catalítica?

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?

Excuse me, teacher! After I introduced methylamine gas, the water became lighter and lighter!

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