Patent DE073812 (http://l2.espacenet.com/dips/viewer?PN=DE073812&CY=gb&LG=en&DB=EPD)
on the production of methylamine from hexamethylentetrenamine.100 Theile Methylenamin (oder ein Gemisch von entsprechenden Mengen Formaldehyd und Ammmoniak) werden mit 2 bis 3l Wasser verdünnt.
Yes, 1893 is quite a time ago.
...followed by adding HCl and zincdust over 3 to 4 hours, after 24 hours basifying and steam extraction into diluted HCl to gain methylamine.HCl by evaporation.
They didn´t use to make a lot of words these days it seems. <sigh>
(Chemicals in authentic spelling now)
The same procedure with Methylamin and Formaldehyd gains Dimethylamin, they state and Aethylaldehyd with Ammoniak gains Aethylamine.
Must have been hard boys, these precursors of HOECHST and IG-Farben.

(java: "methyl amine by catalytic hydrogenation", Chemistry Discourse), I haven't tried it but plan to since SWIJ has shifted his efforts to the P2P route and will need this on his way.
