Ethylene glycol boiling point under vacuum
WebLike ethylene glycol and propylene glycol, glycerol is a non-ionic kosmotrope that forms strong hydrogen bonds with water molecules, competing with water-water hydrogen bonds. This interaction disrupts the formation of ice. The minimum freezing point temperature is about −38 °C (−36 °F) corresponding to 70% glycerol in water. http://www.ciscochem.com/assets/diethylene-glycol-specs.pdf
