identities. That is weak. | Thats not only weak but it is disgusting. But do have any other idea how to
retrieve the information contributed by many to the-hive and stolen by few in a even more disgusting scam (dont forget the download restrictions
imposed before!) besides plain blackmail? You are welcome for I have not - I ran out of ideas and of goodwill. And I am well aware that I expose
myself to retalation - on the net and in realworld. But I am not afraid on the net and I completely reorganized my realworld settings so I dont have
to worry about this either. I would not have dared this if otherwise - Osmium IS a dangerous asshole.
I AM NOT WILLING TO GIVE UP ON THIS. NEVER.

| Try it and you will see. Its just not so easy to dissolve methylamine.HCl out of a heap of ammonium
chloride with which it was cocrystallized. Why? What do I know, encapsulation?, common crystal lattice?, Magic? I dont give a fuck, I tried and saw,
others tried and saw the same and textbook procedures point in the same direction. Of course you will aleways find somebody on the net who found an
easy way to do this better then Vogel or Gattermann. Usually thats just bullshit of course, but its so COOL!

Alright... I wasn't even aware that anything was stolen from the Hive, and to be honest, I haven't even looked into the Hive archives that thoroughly
since it shut down. My point is that your critique may very well be accurate (you seem to know a lot more about it than me). But still I urge you not
to try and blow peoples anonymacy. It's one of the privileges at least I, for one, enjoy on the Internet... At least to the extent that it is possible
these days.
Concerning recrystallization of MeAm from a heap of ammonium chloride - I find the Orgsyn method (Organic Syntheses, Coll. Vol. 1, p.347 (1941); Vol.
3, p.67 (1923)) quite functional actually. I dried the mixture of products over concentrated sulphuric acid in a dessicator, went at it with a mortar
afterwards, then started boiling IPA (instead of EtOH as in the article). It smells like methylamine, it behaves like methylamine, the supposed
ammonium chloride sure as hell tastes like ammonium chloride, and yeah, you get the picture .

Furch how did you work up the nitro reduction of nitromethane using iron and hydrochloric acid if you don't mind telling?
I made methylamine by this route and I remember using IPA to purify it but I don't remember the work up I used to get rid of the iron chlorides and
such.

It was a long, long time ago, and all my notes are gone... But I remember doing it sans alcohol - i.e. water only. When the acidic reduction seemed
complete (I left it to reflux for at least 16 hours), the whole mess was made basic with NaOH, then reflux was continued for more hours... During the
entire reaction a hose was lead from the top of the condenser down into some kind of solvent in a beaker with magnetic stirring.
I would've done it very differently today, but as I've mentioned about five hundred times by now, the cause of the experiment was to confirm that it
worked at all ![;)](./images/smilies/wink.gif)
I don't recommend that "work up" - make up your own instead... It's probably a lot more efficient!

On article page 1664 ( 3rd pg of pdf ) under the heading Alkylureas
" It was found that methylurea and 1,3-dimethylurea reacted with ammonium sulphamate
in a manner analogous to that of urea. Methylamine was isolated from the reaction mixtures."
This is also mentioned in the opening abstract , table IV does not show this perhaps an ommision ?

I thought methylamine gas dissolved nicely in water, so why are you guys doing it in HCl?

Methylamine gas is usually dissolved in water to make 40% aqueous solution or sometimes methanol but I think they are referring to methylamine hcl,
the hydrochloride salt form.
