Dobrý deň, na aké riešenie sa pýtate a čo je to metóda hydrogenácie? Môžete byť presnejší?

Môže sa metylamínhydrochlorid vyrobiť do 60 % vodného roztoku a Môže tento roztok fungovať pri redukčnej alkylácii metódou katalytickej hydrogenácie ?

Mám na mysli použitie plynného vodíka namiesto hliníkovej fólie

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?
