I stumbled over this quite old (1893) german
Patent DE073812
on the production of methylamine from hexamethylentetrenamine.
They tell no yields but I would be interested if somebody knows more on this way or has tried it already:
100 parts (what does this say?) of hexamethylenamine are dissolved in 2 to 3 liters water at roomtemperature. Than over 3 to 4 hours the for the reduction necessary amounts (they don´t disclose how much this is
) of HCl and zincdust are added. After 24 hours the solution gets basified and the methylamine steamdistilled in diluted HCl to yield methylamine.HCl.
Then follows a part on making dimethylamine from methylamine what tells me that the first procedure should yield quite pure methylamine.
Comments please!
Sounds not bad for me, roomtemperature and if the steam is going into water and not HCl you should get aqueous methylamine what may be preferable sometimes.
