    Alchol percentage for flammable?

    Post  master5o1 on Mon Apr 20, 2009 1:57 am

    What is the minimum percentage of alcohol for it to be flammable?

    I think ~45% or so.

    If you are talking about it flaring up straight away then the percentage may need to be higher. However it will catch on fire at that percentage with a bit of heating. It will catch fire at 20 percent once the liquid has got to a certain temp.

    Maybe I should have been more specific:

    Standard Conditions:
    temperature of 20 or 25 °C
    atmospheric pressure of 101.325 kPa

    Are you looking at making your own fuel. My dad did that with his lawn mower. It ran fine with his 80% proof grog in it.
