I have some old DMF which reeks of triethylamine - I was hoping to distill the TEA off for later use as a proton scavenger. I figured there would be
no issue with this, but as I am unsure of the mechanism for degradation of DMF, I figured I'd ask to make sure that there is nothing I'm overlooking,
like possibly the TEA abstracting protons prior to collection? - rendering it useless. Any issues here?

Let us see
Me2NCOH => Et3N
not very likely, lengthening carbon chains by CH2 for starters. I'd suspect dimethyl amine as the main portion of the odor. Ozone - 6-11-2010 at 19:14
It is most likely dimethylamine*, a common (and often problematic) contaminant in DMF.

i guess i remember reading somewhere that TEA was a major breakdown product of DMF...i didn't know how/why, but you bring up a good point =p
