A research team from Ford Motor Company and the University of Copenhagen has performed a systematic study of the vapor pressures of single and dual-blends of different alcohols with potential to be used as biofuels, including methanol; ethanol; 1- and 2-propanol; and 1-, 2-, i-, and t-butanol.

As part of the study, they demonstrated a simple method to prepare dual-alcohol-gasoline blends with Reid vapor pressures (RVPs) “indistinguishable” from that of the base gasoline. Their paper was published online 21 May in the ACS journal Energy & Fuels.
