Organization: ASTM
Publication Date: 1 March 2015
Status: inactive
Page Count: 4
ICS Code (Aliphatic hydrocarbons): 71.080.10
ICS Code (Liquid fuels): 75.160.20
scope:

This specification covers butanol intended to be blended with gasoline at 1 to 12.5 volume % for use as an automotive spark-ignition engine fuel. 

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.

The maximum limit on blending is not a performance limit but a current regulatory limit in the United States. 

This specification covers three butanol isomers:1- butanol, 2-butanol, and 2-methyl-1-propanol. This specification specifically excludes 2-methyl-2-propanol (that is, tert-butyl alcohol). 

Tert-butyl alcohol has different physical properties (melting point, water miscibility) than the other three isomers. 

 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 

This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
