Sveiki, kokio tirpalo klausiate ir kas yra hidrinimo metodas? Ar galite patikslinti?

 

[real4]

Ar galima metilamino hidrochloridą paversti 60 % vandens tirpalu ir Ar šis tirpalas gali veikti redukcinio alkilinimo katalizinio hidrinimo metodu ?

 

[real4]

Turiu omenyje vandenilio dujų naudojimą vietoj aliuminio folijos

 

[G.Patton]

Žmogau, aš negaliu skaityti tavo minčių. Ko hidrinimas?
Taip

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?
