Hartelijk dank voor deze gratis kennis, kunt u alstublieft
Deze methylamine-oplossing worden gemaakt in 60%, en kan het werken voor

Hydrogenatie methode. bedankt voor het beantwoorden

Hallo, welke oplossing vraagt u en wat is hydrogeneringsmethode? Kunt u preciezer zijn?

 

[real4]

Kan van methylaminehydrochloride een 60% wateroplossing worden gemaakt en kan deze oplossing werken bij reductieve alkylering via de katalytische hydrogeneringsmethode?

 

[real4]

Ik bedoel waterstofgas gebruiken in plaats van aluminiumfolie

 

[G.Patton]

Gast, ik kan je gedachten niet lezen. Hydrogenatie van wat?
Ja

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?

Does this video summarize what is being done?

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

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