Ethanol (also called ethyl alcohol, grain alcohol, drinking alcohol, or simply alcohol) is an organic compound with the chemical formula CH 3 CH 2 OH. It is an alcohol , with its formula also written as C 2 H 5 OH , C 2 H 6 O or EtOH, where Et stands for ethyl .
The alc/vol value of a beverage is always higher than the ABW. Because ABW measures the proportion of the drink's mass which is alcohol, while alc/vol is the proportion of the drink's volume which is alcohol, the two values are in the same proportion as the drink's density is with the density of alcohol.
The density values for chemical fuels do not include the weight of the oxygen required for combustion. ... (85% ethanol 15% gasoline by volume) 33.1 25.65 [citation ...
In contrast, ethanol critics [who?] contest the benefits of E85 by focusing on the fact that E85 has 33% lower heating value compared to the higher heating value of gasoline. However comparing energy expressed as a value of heat does not reflect the total work from an Otto Cycle [citation needed].
Pure ethanol provides 2/3 of the heat value available in pure gasoline. In the most common calculation, that is, the BTU value of pure gasoline vs gasoline with 10% ethanol, the latter has just over 96% BTU value of pure gasoline.
