WebOct 8, 2013 · The lower heating value (energy density) of 1-butanol is close to that of gasoline. This could have a positive effect (decrease) on the fuel consumption comparable to ethanol [].The Reid vapour pressure of 1-butanol is only 2.3 kPa. Ethanol is classified as a primary alcohol, meaning that the carbon that its hydroxyl group attaches to has at least two hydrogen atoms attached to it as well. Many ethanol reactions occur at its hydroxyl group. In the presence of acid catalysts, ethanol reacts with carboxylic acids to produce ethyl esters and water:
