Kann Methylaminhydrochlorid in eine 60%ige Wasserlösung überführt werden und kann diese Lösung bei der reduktiven Alkylierung mittels katalytischer Hydrierung eingesetzt werden?

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!
