What intrigues me about the original question is what actually happens when
you heat a mixture (say 50-50) of water and ethylene glycol to its boiling
point.  Does the ethylene glycol become more concentrated or do they
vaporize together as happens when we use acetone for examle to dry lab
glassware.
  I suppose there is somewhere to look this up.  If I wasn't retired I
could try the experiment...but then I wouldn't have so much time to fight
the rust on my vanagons.    :-)
