Why oh Why (I hope this is in the correct zone)
First there were weird looking crystals of Methylamine HCl, next moment all that sits there is a group of clear liquid globules - which themselves will not freeze!
What a damn waste of effort that was, what went wrong?
30%Formaldehyde w/w & 25% Ammonia w/w = Hexamine
Hexamine & 33% HCl w/w = Ammonium Chloride & Formaldehyde ?(yeah- as per Rhodiums page "chemhack")
HEAT with Ammonium Chloride & Formaldehyde = `among other things` Methylamine HCl
After doing the hot alcohol / icy cold alcohol purification process a few times SWIM thought she'd cracked it, and then this! globules ....useless globules man!

If you want to produce methylamine than you should try to follow the procedure from Vogel as closely as possible.

Remember what Eleusis said? To get this stuff dry before recrystallizing, you gotta heat it until the fumes start coming off. (sublimination of AmCl) Then recrystallize with MeOH, wash with acetone and go from there. If it's very humid, your crystals can turn out wet.

Better to follow the Vogel procedure.
