• Boiling Points of Ethanol, Methanol, and Isopropyl Alcohol

    The boiling point decreases as atmospheric pressure decreases, so it will be slightly lower unless you are at sea level. Here is a look at the boiling point of different types of alcohol. The boiling point of ethanol or grain alcohol (C 2 H 5 OH) at atmospheric pressure (14.7 psia, 1 bar absolute) is 173.1 F (78.37 C).
