For those who can't get their hands on a sufficient amount of gaseous Methylamine, what would be the method of choice to make it in sufficient amounts themselfs, fast and easy, without any difficulty to obtain precursor chemicals and/or complicated machinery?
Lets look first at these 2 threads :

(Methyl_Man: "Methanolic MeAm via Al/Hg/MeNO2?", Novel Discourse)Methanolic MeAm via Al-Hg-MeNO2 Hive Novel Discourse
and then two simple methods prevail :
1. Formaldehyde + Ammoniumchloride --> heat 4 hrs at 105 °C --> MeAm in huge batches.
2. Hexamine + HCl under vacuum refluxing.
I would like to have a memorable writeup from anyone who has experience with both methods, or any other method which falls in this category.
Any link to past writeups is also welcome, I remember vaguely that we had quite some discussion going on on both subjects, 1 in the newbee forum in the very beginning of the forum, and 2 also somewhere there and prolly a lot of posts in other forums.
It's time we compile all this info in this thread, and then I can place it in the sticky thread on top of this forum.
We have much to much shattered pieces of important info lying around in numerous forums, its time to compile all that badly needed MeAm gas info in one place.
There is also a long forgotten easy method of making small or huge amounts of MeAm gas starting from MeNO2 (nitromethane, methylnitrite), carefully warming it up in a vessel where a vertical glass or metal pipe is placed on top of it, filled with an oxidized Nickle wool catalyst and a heater-coil around the pipe, there where the Nickle-wool sits, and introducing a small stream of H2 gas just under the Nickle-wool to start the conversion to MeAm gas.
The MeAm can then directly be bubbled in to a cooled container with dry methanol. This can be converted to a continuous operation, see the
huge picture?
The tricky thing seemed to be the necessairy oxidation of the Nickle-wool catalyst to a black colour, but not overly difficult, perhaps sending a amperage of sufficient power through a coiled Nickle-wool to red hotness in a container with oxigen will do the trick. Or just heating it in a gasflame feeded with oxigen also, and then dispersing it in a beaker filled with oxigen, until the oxigen is used up, and the wool is blackened.
Anyone having ideas about this procedure, please feel free to hop on this thread too. LT/
