Metüülamiini freebase lahuse valmistamine

[real4]

Pl
Tänan teid väga selle tasuta teadmiste eest, palun võite
Seda metüülamiini lahust teha 60%-liseks ja kas see võib toimida

hüdrogeenimismeetodiga. aitäh vastamise eest

 

[G.Patton]

Tere, millist lahendust te küsite ja mis on hüdrogeenimismeetod? Kas te saaksite täpsemalt öelda?

 

[real4]

Kas metüülamiinvesinikkloriidist saab teha 60%-lise vesilahuse ja Kas see lahus toimib reduktiivses alküülimises katalüütilise hüdrogeenimismeetodi abil ?

 

[real4]

Ma pean silmas vesinikgaasi kasutamist alumiiniumfooliumi asemel

 

[G.Patton]

Kutt, ma ei oska teie mõtteid lugeda. Mille hüdrogeenimine?
Jah

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?
