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. Evaporative emissions from gasoline—volatile organic compounds (VOCs)—are precursors to the formation of tropospheric ozone and contribute to ground-level ozone. Credit: ACS, Andersen et al.
