As a side note, if you don't happen to have Glycerin available and are in a bind for a hypergolic reaction, then all you have to do is find a car.

Anti-freeze contains either Propylene Glycol (PG) in the "safer" version or Ethylene Glycol (EG) in non pet-safe type. Both have boiling points well above that of water, thus making them easy to distill through an open boiling method. Note for the stupid, "Don't inhale the fumes."

Both Glycols will have a similar reaction with Potassium Permanganate, although all other things being equal, EG reacts with the Potassium Permanganate in about half the time, and PG in about twice the time of Glycerin.
