Significance and Use
A1.5. Significance and Use
A1.5.1 Butanol is a potential blendstock for blending with gasoline provided that it meets a purity specification of >96.0 % butanol in accordance with Specification D7862. This test method provides a method of determining the percentage of butanol (purity) of the butanol for blending with gasoline.
1.1.1 Butanol contains 22 mass % oxygen. The mass % of oxygen of a butanol blend with gasoline depends on the volume % of butanol blended, the density of the butanol isomer and the density of the base blendstock.
