Study of Vapor Pressures of Gasoline-Alcohol Blends Finds That Dual-Alcohol Blends Can Result in RVPs Identical to That of Gasoline

Green Car Congress

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.
