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

MAY 23, 2010

RVPs (predicted DVPE) of single- and dual-alcohol blends in gasoline with different relative proportions of ethanol and 1-butanol. The alcohols and hydrocarbons in the gasoline formed non-ideal mixtures with RVPs that were higher than would be expected for ideal mixtures. Credit: ACS, Andersen et al. Click to enlarge.

d) further provides for alcohol blends as follows: Special provisions for alcohol blends. (1) In February, 2009, the US EPA granted Renergie, Inc. Hydrous ethanol (also sometimes known as azeotropic ethanol) typically ranges from 186 proof (93% ethanol, 7% water) to 192 proof (96% ethanol, 4% water).
