On the Hive, I remember a thread where someone suggested separating NH4Cl from MeNH2.HCL by attaching a tube to the flask containing the the mix, then
droping NaOH into it and testing by holding a flame to the end of the tube to tell when MeNH2 comes through, meaning that NH4Cl is gone.
Is this completly dangerous. What's the chance of getting a flameback into the flask

Put a check valve in the line same as is used in
an oxy-acetylene torch head.
Even an orifice would provide some back pressure which
would be safer than nothing.
Seems that the ammonia and methylamine gases would
mix rendering this a dubious procedure at best.
