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.

Six of these blendstocks had the fewest significant practical barriers to adoption and use: di-isobutylene; ethanol; isobutanol; n-propanol; isopropanol; and a fusel alcohol blend. All the top-performing blendstocks showed potential to be produced at a competitive cost. Gaspar, Daniel J., West, Brian H., Moore, Cameron M.,
