Pl
Thank you very much for this free knowledge, please can
This methylamine solution be made into 60%, and can it work for

Hydrogenation method. thanks for replying​

Hello, what solution do you ask and what is hydrogenation method? Can you be more precise?

 

[real4]

Can methylamine hydrochloride be made into 60% water solution and Can this solution work in reductive alkylation via catalytic hydrogenation method ?

​

 

[real4]

I mean using hydrogen gas in place of aluminum foil

 

[G.Patton]

Dude, I can't read your mind. Hydrogenation of WHAT?
Yes

Teacher, may I ask if after adding sodium hydroxide to the water and stirring until dissolved, it will no longer be transparent！

 

[B APPLE]

Teacher! May I ask if there is a diagram for the 40% synthesis method of methylamine water?

 

[B APPLE]

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?

 

[B APPLE]

If there is no reaction after adding methylamine hydrochloride to the sodium hydroxide solution, do we still need to add 869 grams？

 

[B APPLE]

Do I need to seal when introducing amine gas？

thank you for this valuable help! That said, I would like you to enlighten me -5. A silicone tubing with vial connector is attached to the reaction vial with methylamine free base. what material should we use to hang this silicone pipe?
