OK, whoever made that ketone decide to add some probably relevant information here :
1) Made by Wacker oxidation in DMF, even though his fellow has been dreaming with peracetic. This guy has been able to make good ketone and aminate it and etc. this way before.
2) I have no idea of what formic acid smell like, but I had a bad experience with a second hand pump once, when I exchanged the pump oil ( quite dirty ) it smelled exactly like the above described smell. The vacuum was much worse than the spec value, more than 20 mm Hg which is the top range value of my vacuum gauge. Pump long gone, sold it by half the price or less, next I ordered a brand new one, still have it, so far working and in good condition. Main reason I bought such a pump is that I paid cash, no receipt, bad idea.
Maybe someone can confirm this is or not the way formic acid smells like. Again, it smells like acetic acid and HCl.
3) I am aware ketone purity is an important issue, of course. I plan to test it with sodium metabisulfite and maybe to redistill it.
4) Sorry it if sounds silly. I hope I have explained what I mean now.
