Activation energies of alcohol fuels have been determined through droplet combustion and extinction experiments using droplet suspension technique in a low pressure environment to minimize the effect of buoyance. Results show that the activation energies determined are 41.4 kcal/mol for ethanol, 47.6 for 1-propanol, 48.4 for 1-butanol, 40.0 for 2-butanol, 48.0 for 1- pentanol, 50.8 for 1-hexanol and 51.7 for 1-decanol.
