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. At high blending concentrations (70-85%), however, the propanols and butanols may produce problematically low RVPs. Resources. Nielsen (2010) Vapor Pressures of Alcohol-Gasoline Blends.
