1、Designation: D7862 13Standard Specification forButanol for Blending with Gasoline for Use as AutomotiveSpark-Ignition Engine Fuel1This standard is issued under the fixed designation D7862; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revi
2、sion, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers butanol intended to be blendedwith gasoline at 1 to 12.5 volume % for use
3、as an automotivespark-ignition engine fuel.1.1.1 Butanol contains 22 mass % oxygen. The mass % ofoxygen of a butanol blend with gasoline depends on thevolume % of butanol blended, the density of the butanol isomerand the density of the base blendstock.1.1.2 The maximum limit on blending is not a per
4、formancelimit but a current regulatory limit in the United States.1.2 This specification covers three butanol isomers:1-butanol, 2-butanol, and 2-methyl-1-propanol. This specifica-tion specifically excludes 2-methyl-2-propanol (that is, tert-butyl alcohol).1.2.1 Tert-butyl alcohol has different phys
5、ical properties(melting point, water miscibility) than the other three isomers.1.3 The values stated in SI units are to be regarded asstandard. No other units of measurement are included in thisstandard.1.4 This standard does not purport to address all of thesafety concerns, if any, associated with
6、its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.

16、 theterms used in a particular context are clearly understood.3.2 Definitions:3.2.1 gasoline, na volatile mixture of liquidhydrocarbons, generally containing small amounts ofadditives, suitable for use as a fuel in spark-ignition, internalcombustion engines.

D48143.3 Definitions of Terms Specific to This Standard:3.3.1 butanol, nbutanol or butyl alcohol refers to1-butanol, 2-butanol, and 2-methyl 1-propanol, three isomericalcohols with the molecular
18、 formula C4H9OH, either individu-ally or as mixtures.4. Performance Requirements4.1 ButanolButanol shall conform to the requirementsshown in Table 1 at the time of blending with a gasoline. (SeeNote 2.)NOTE 2Commercial processes used to manufacture butanol frombiological feedstock typically yield so
19、me fusel oil or alcohols such aspentanol and other higher alcohols.4.1.1 For purposes of determining conformance with thesespecification limits, an observed value or a calculated valueshall be rounded “to the nearest unit” in the right-mostsignificant digit used in expressing the specification limit
20、, inaccordance with the rounding method of Practice E29. For aspecification limit expressed as an integer, a trailing zero issignificant only if the decimal point is specified. For a specifiedlimit expressed as an integer, and the right-most digit isnon-zero, the right-most digit is significant with
21、out a decimalpoint being specified. This convention applies to specifiedlimits in Table 1 and will not be observed in the remainder ofthis specification.4.2 Other PropertiesLimits more restrictive than thosespecified above, or the specification of additional propertiessuch as color, may be agreed up
22、on between the supplier and thepurchaser.5. Workmanship5.1 The butanol shall be visually free of sediment andsuspended matter. It shall be clear and bright at the ambienttemperature or 21C, whichever is higher.5.2 The product shall be free of any adulterant or contami-nant that can render the materi
23、al unacceptable for its com-monly used applications.5.2.1 Manufacturers and importers of butanol shall avoidbutanol contaminated by silicon-containing materials. Siliconcontamination of gasoline-oxygenate blends has led to fouledvehicle components (for example, spark plugs, exhaust oxygensensors, ca
24、talytic converters) requiring parts replacement andrepairs.5.2.2 Manufacturers and importers of butanol shall avoidbutanol contaminated by acetone. Acetone contamination ofgasoline-oxygenate blends can degrade elastomers used in fuelsystem components as well as paint and/or clearcoat finishesused on
