Мethylamine hydrochloride

[mejdubulok]

greetings, friends. Tell us how to work with methylamine hydrochloride? Is it necessary to dissolve it or can it be put directly into the reactor? thanks.

 

[Frit Buchner]

Depends on the synthesis, but in many cases you should neutralize it to the conjugate base, methylamine.

Frit BuchnerThank you dear friend. what is the method? if you can explain the process. thank you.

 

[Frit Buchner]

You just basify the solvent it is in to neutralize the lewis acid (HCl in this case) oftentimes you can just add a solution of (for instance) NaOh dropwise to pH....? 3 I'm guessing, I'll look it up, and the methylamine will separate and seperatory funnel it. I'm guessing, I'll look it up. I figured you could precipitate it, but realized it's a liquid ( gas dissolved in a liquid, but not soluble in NaOh

 

[Frit Buchner]

Looks to me like you neutralize it with NaOh and run it to a gas washer or some other suitable device to catch the methylamine gas in water.

There is a topic by G Patton, how to generate and dissolve methylamine base in alcohol. You then use the alcohol solution for your synthesis.

If you mean the reaction with phenylacetone. First, neutralize the methylamine with acid chloride, then heat until the water evaporates. Store in a closed container in the freezer until it is used for 6 months. The amount used in the reaction is to add one third of the weight of methylamine hydrochloride, anhydrous sodium hydroxide with methanol or ethanol to the reaction.

rubarzanWell say so, in some reactions methylamine 40% is used. as in some countries this solution is allowed. and hence the question: if i have methylamine hydrochloride, do i need to do additional manipulations with it or can i dilute it with water at once? to get a solution. to prepare 4mms.

I'm writing through a translator. Sorry.

mejdubulokIf it doesn't say " a 40% solution of methylamine HCL " then you need to neutralize it to methylamine.

Frit BuchnerOkay, thank you. but how can it be done?

 

[T0lek511]

If you react methylamine hydrochloride with NaOH you can make methylamine gas.

 

[mejdubulok]

thanks to all. I found a solution.

 

[jotoy]

thanks to all. I found a solution.

mejdubulokHi can you explain your solution?

I need your help. I have plenty of methylamine hydrochloric crystals, raw material, and how can I dilute it? Thank you. I would be glad if you could help me.
