O cloridrato de metilamina pode ser transformado numa solução aquosa a 60% e esta solução pode funcionar na alquilação redutora através do método de hidrogenação 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?
