RVPs (predicted DVPE) of single- and dual-alcohol blends in gasoline with different relative proportions of ethanol and 1-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.

Isoprene, a five-carbon diene formed naturally in plants and animals and a precursor of ozone, contributes more than 40% of these emissions. There is much more isoprene emitted to the atmosphere than all of the gases (gasoline, industrial chemicals) emitted by human activities, with the important exceptions of methane and carbon dioxide.
