Najlepša hvala za to brezplačno znanje, prosim, lahko
se ta raztopina metilamina pretvori v 60 % in ali lahko deluje za

metodo hidrogeniranja. hvala za odgovor

Pozdravljeni, za katero raztopino sprašujete in kaj je metoda hidrogeniranja? Ali ste lahko bolj natančni?

 

[real4]

Ali lahko metilamin hidroklorid pripravimo v 60-odstotni vodni raztopini in Ali lahko ta raztopina deluje pri reduktivni alkilaciji z metodo katalitske hidrogenacije ?

 

[real4]

Mislim na uporabo plinastega vodika namesto aluminijaste folije

 

[G.Patton]

Človek, ne morem ti brati misli. Hidrogeniranje ČEGA?
Da

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？

 

[Eddybeaumont]

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?

Does this video summarize what is being done?

 

[Chemistry lntern]

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

 

[Chemistry lntern]

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