Mange tak for denne gratis viden, kan du venligst
Kan denne methylaminopløsning laves til 60 %, og kan den bruges til

Hydrogeneringsmetode. tak for svaret

Hej, hvilken løsning beder du om, og hvad er hydrogeneringsmetoden? Kan du være mere præcis?

 

[real4]

Kan methylaminhydrochlorid laves til en 60 % vandopløsning, og kan denne opløsning fungere i reduktiv alkylering via katalytisk hydrogeneringsmetode?

 

[real4]

Jeg mener at bruge brintgas i stedet for aluminiumsfolie

 

[G.Patton]

Jeg kan ikke læse dine tanker. Hydrogenering af HVAD?
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?
