WebMar 28, 2011 · Pure ethanol has a flash point of only 55 degrees F. Add 15 percent water and the flashpoint rises to 68 degrees F. Ethanol is still flammable mixed with water. That means that if you had a spill involving a 100,000 gallon tanker you could dilute it with as much as 900,000 gallons of water and still have a fire hazard. WebJul 1, 2007 · For ethanol, the lower flammability limits (LFL) decreases from 3.7% for pure vapor to 3.2% with saturated water vapor. For acetonitrile, the decrease is from 4.2% to 3.8%.
