An ethanol-water solution that contains 40% ABV (alcohol by volume) will catch fire if heated to about 26 =B0C (79 =B0F) and if an ignition source is applied to it. This is called its flash point.[80] The flash point of pure ethanol is 16.60 =B0C (61.88 =B0F), less than average room temperature.
The flash points of ethanol concentrations from 10% ABV to 96% ABV are shown below:[81]
=B7 10% — 49 =B0C (120 =B0F)
=B7 20% — 36 =B0C (97 =B0F)
=B7 30% — 29 =B0C (84 =B0F)
=B7 40% — 26 =B0C (79 =B0F)
=B7 50% — 24 =B0C (75 =B0F)
=B7 60% — 22 =B0C (72 =B0F)
=B7 70% — 21 =B0C (70 =B0F)
=B7 80% — 20 =B0C (68 =B0F)
=B7 90% — 17 =B0C (63 =B0F)
=B7 96% — 17 =B0C (63 =B0F)

Subject: [DCHAS-L] 20% Ethanol
Does anyone have flashpoint data on 20% ethanol in water they can share?
Thanks
