Metilamīna brīvās bāzes šķīduma sagatavošana

[real4]

Pl
Liels paldies par šīm bezmaksas zināšanām, lūdzu, varat
Šo metilamīna šķīdumu var pārvērst 60%, un vai tas var darboties

Hidrogenēšanas metode. paldies par atbildi

Labdien, kādu šķīdumu jūs jautājat un kas ir hidrogenēšanas metode? Vai varat būt precīzāks?

 

[real4]

Vai metilamīna hidrohlorīdu var pagatavot 60% ūdens šķīdumā un Vai šis šķīdums var darboties reduktīvā alkilēšanā, izmantojot katalītiskās hidrogenēšanas metodi ?

 

[real4]

Es domāju, izmantojot ūdeņraža gāzi alumīnija folijas vietā

 

[G.Patton]

Dude, es nevaru lasīt tavas domas. KAS hidrogenēšana?
Jā

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?

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